China has found a solution to tariffs for Amazon sellers in the US. The problem is that it is illegal

by

The commercial war between the United States and China can shoot so many prices That the list is, a priori, endless. However, this 145% tariff figure imposed by the Trump administration (later Replicated by Beijing), it affects more products than others, and within that giant on online purchases called Amazon, the problem is much more fat for some vendors than for others. In China they have found a solution, although it does not seem legal. Fraud hidden behind shipments. I told it exclusively Fortune weekend. The rates imposed by the Trump administration of Chinese imports, which have reached such high levels Like that 145% We were talking about, not only have they destabilized great American retailers and sellers In Amazon, but they have also put in check the Chinese manufacturers and distributors who feed those supply chains. In response to this increasingly hostile commercial environment, several Chinese suppliers have begun to offer their US clients a “solution” as simple as illegal: falsify the declared value of imported products to reduce tariff load. It is, without any type of rodeos, a type of customs fraud. Illicit offers in digital tray. The medium lo He explained with examples. In messages sent by email and through the Wechat platform (then obtained by Fortune) at least half a dozen Chinese suppliers explicitly proposed to an American brand of domestic goods with a wide presence on Amazon that Subdeclara The value of its imports. “Many companies in the United States use invoices with minor values ​​to facilitate customs office and reduce rates,” wrote one of them. Another was still More direct: “We can modify the declared value in commercial invoices to help with tariff costs.” These proposals apparently have been frequent and formulated with total normality, as if they were part of the usual treatment. In some cases, suppliers added the option to use the shipping method Delivery Duty Paid (DDP), where the supplier assumes customs management and is responsible for manipulating the declared value of the shipment, thus creating a kind of deliberate barrier between the American seller and customs. Everything, of course, with the aim of relieving the tax burden, but assuming significant legal risks. A mined land for small importers. According to the medium, the founder of the American company involved (which anonymity requested so as not to compromise its usual suppliers) expressed concern that many small companies They can fall In these traps without fully understanding the legal consequences. Such and As he saidone of its suppliers said that this tactic is already common among competitors based on China. It is precisely this type of practices that, according to him, distorts the playing field: Chinese vendors who falsify the value of their shipments not only avoid high tariffs, but also obtain a direct competitive advantage over US vendors who follow the rules. From suspicion to confirmation. Apparently, suspicions about this type of practices are not new. Many American sellers have been complaining that their rivals in China could be Systematically subdeclating The values ​​of your products. Be that as it may, last week the issue exploded within the Amazon sellers community after a Chinese consultant published An entrance to LinkedIn stating that “the declared value of a typical container from China to the United States usually ranges between 5,000 and 10,000 dollars”, a figure that US vendors consider ridiculously low, especially in categories such as “home and garden”, where products such as furniture significantly raise real value. Play within legality. Options under the legal framework? Fortune said that in the face of pressure, some Chinese suppliers have begun to Offer small discounts in wholesale prices as a palliative measure, but that barely touch the surface of the problem. Others mention the possibility of Move production To other countries with lower tariffs, although they recognize that this alternative can only materialize over time. Meanwhile, illegal offers seem to continue on the table. The combination of punitive rates, unfair competition and lack of effective customs supervision has created a scenario where the incentive to the trap overcomes The will to respect the norms. A fraud without punishment. It is the last of the aid legs to explain this type of movements. Impunity seems to be a central ingredient of the crisis. Several American businessmen expressed to Fortune his frustration for the absence of consequences for those who commit customs fraud from China. The control mechanisms do not seem to be prepared to respond with the necessary forcefulness, and each container that enters undervalued represents not only a loss of fiscal income, but also a direct affront to the principle of loyal competition. In other words: the system, as it is, does not seem to punish the cheater. And as long as that does not change, the temptation to cross the line will remain there, in this case, disguised as a simple commercial proposal in an entrance tray.

The European car industry has a problem with US tariffs. Your solution is surprising: India

by

An attack in a commercial war, a negotiation proposal and a closed door to lime and song. This can be summarized in the last days in the relationship between the United States and the European Union. On April 2, Donald Trump confirmed that the 25% tariffs on cars and the pieces for their production that will go through their borders. At the same time, he also confirmed that he would apply tariffs to almost all countries in the world. The base rate of these last tariffs is 10%. From there, the United States will apply tariffs that climb depending on the commercial deficit that has with those countries and that, according to its president, apply hidden commercial barriers. The European Union will pay 20%. Japan 24%. The threat already amounts to 104% for China. The answers have been diverse. China answered the first tariffs raising commercial barriers, which has cost him the threat we wrote above. Japan has sent emissaries to try to reach an agreement. Europe has put its own proposal on the table: 0% tariffs in the two directions For cars and industrial goods. The answer has been overwhelming. For Donald Trump this is not enough and is not open to negotiate in those terms. In the air a trade is at stake that in 2024 moved 38.9 billion euros. They are the ones paid by the United States for cars from Europe. To them we must add those manufactured by European companies in Mexico and Canada, to which these commercial barriers are also applied. The measure is hard and puts a sector, that of the automobile, which uses more than 13 million people in Europe and did not cross their best moment. In China, European manufacturers are finding huge difficulties in placing their cars now that the market has set their eyes on local manufacturers. In the United States, the production of the product only leaves three ways. One of them is to stop sending cars or stop selling them, as Volkswagen and Mercedes are doing with some models. The second option is manufacture locally But limiting the pieces that arrive from the outside, which is a expensive reinvestment. The third, and last, is to absorb tariffs to a greater or lesser extent and try to limit the rise in the final price. All these options attack the results account of the great European manufacturers. Good because they will sell less, because it will cost them more expensive to manufacture or for the sum of both conditions. Therefore, they already look where their factories or their products can be transferred. India seems to open the arms. 100% to 10% The Indian market is unexplored by large European manufacturers. The difficulties in operating there are maximum. The example is totally contrary to Japanese. In the Japanese country There are no tariffs to the importation of vehicles for local sale. However, the client is particular. In the big cities You can barely sell cars Because regulations on space force a parking space. They do not require Kei Caran extremely narrow and cheap type of car that in Japan dominates perfectly. India, however, is a very protectionist country. Tesla knows the challenge. In 2016 he already tried to enter there opening reserves of their cars for 1,000 euros. Almost a decade later their owners did not have the car or money. Tariffs are 15%… as long as Do not enroll more than 8,000 units When it comes to an electric. An extremely low figure that discourages the industry to sell large amounts of vehicles. Especially since they demand three -year investments seen In addition, so far they have had another problem. The potential client needs extremely cheap cars and with Very specific technical issuesas a free height to the ground higher than usual since the roads are in very poor condition. Adapting cars is a company to spend money on developing a product that must compete in extremely low prices. However, Europe seems to be willing to reach an agreement with India. And India is willing to listen to Europe and open the door. This is what they maintain in Reuters which ensure that the European Union and the Asian country are looking for a Agreement to reduce tariffs of import that are now 100%. In the news agency they point out, however, that although India is willing to reach a 10%tariff. Local manufacturers such as Tata or Mahindra press to impose their conditions. These are not going down 70% in tariffs on gasoline cars and gradually reduce tariffs up to 30% in successive phases. Of course, in the case of the electric car they do not want to reduce tariffs until 2029. Negotiation comes just when the United States has also pointed in the same direction. As we counted, Tesla has long wants to enter the market but Negotiations have intensified Since 2023. A four million vehicle market is juicy enough to seek solutions now that relations between the United States and Europe harden. Manufacturing in India is also an opportunity for manufacturers to give out to their lowest vehicles. The industry has long proclaimed that selling electric cars of 20,000 euros is not profitable in current conditions. That’s why Automotive News He pointed out that the Volkswagen Group has been evaluating this possibility. Carlos Tavares, at the head of Stellantis in 2022, I also pointed that India was one of the markets to conquer. And, according to ReutersByd has also shown interest in entering the country.

Without tolls, the AP-7 has become hell. The solution passes through speed limits of 60 km/h

by

The AP-7 is known as the Mediterranean highway. It is an essential axis for Spanish traffic since it allows to circulate without interruptions between Tarragona and Alicante. And if we add their links to other roads, it allows to circulate between France and Cádiz. A road, yes, that until 2021 was marked by various tolls. Some sections, in fact, They were one of the most expensive in Spain. The road, however, is fought from the Tolls in 2021. What it was A historical claim In the area it soon became a problem. In its first year, the road saw tourism traffic increasing 40% and 80% of trucks, collected in The country. The obvious result: more jams, more accidents … and more jams accordingly. Specifically, only the first year the AP-7 concentrated 20% of the dead on the road throughout Catalonia. A figure that contrasts with the trend of the rest of the country where the deceased on the road They concentrate on secondary roads. The New free routewith France at one end and Barcelona to one of its sides, it has turned the road into a parade of merchandise vehicles. And the problem is such that since then solutions are being sought. First with a partial reduction of speed limits. An action that has arrived in 2022 and added 82 kilometers. The next step is to copy Europe. A solution to the European Since then, the AP-7 situation has not improved much. Although mortal figures have been reduced over time, only in 2024 more than 1,600 incidents on the road. The response of traffic managers has been to reduce speed. How much? It will depend on the Meteorology and traffic congestion. Because the proposal goes through a changing management of the maximum speed of the road. A solution that already applies to other roads in Europe and that can reduce the maximum allowed limit to 60 km/h. The person in charge of announcing the measure was the Minister of Interior, Núria Parlon. They point out in The newspaper that this section of variable speed will extend for 150 kilometers between Maçanet de la Selva (Girona) and the Vendrell (Tarragona). For this, panels controlled by artificial intelligence will be implemented that will limit the traffic speed based on the different circumstances that are giving. The measure takes as reference what happens, for example, In German autobahn. On these roads there is no defined speed limit. In fact, if circumstances accompany, There is no speed limit. But at nightfall, when it rains or if there are works on the road, the panels show a speed limit equal to or less than 130 km/h. The operation is exactly the same as on the German roads but the director of the Catalan Traffic Service (SCT), Ramon Lamiel, already warns in an interview with EFE: The speed can be reduced up to 60 km/h at some points. At the moment, the project is in the development phase by the Servei Català de Trànsit (SCT)who has the competitions on Catalan roads. In the second quarter of the year it should be written to be able to get it as a tender. They explain in The countrythat the intention is to deploy a progressive reduction in the maximum speed before the driver is suddenly with a bottling that forces him to reduce the speed much more drastic. Speaking to the newspaper, Lamiel insists that speed will be reduced Only in the most congested sections since they believe that the increase in accidents is derived from a greater volume of traffic and not from the danger of the road. In addition, he points out that they already proposed this measure to extend it nationwide by the roads that are the competence of the DGT but that its proposal was dismissed. The truth is that The theory says that when we circulate more slowly, traffic jams are reduced. Atasco are a sum of errors. When we circulate at a lower speed, the time to alleviate errors is greater and these are reduced. It is a matter of effectiveness and not so much speed. Traffic circulates more slowly but flows. If we circulate too fast, the braking are more abrupt, it costs more to recover a sustained speed and, little by little, we end up stucking the road.

China became famous for its eternal working days. The solution has been to throw employees at their time

by

The Reduction of the working day It seems to be a path of no return that many countries have proposed to move. Some, Like GreeceThey do not do it with a determined step. Instead, others whose self -denial It seemed immovable, they are surprising the world with day reduction measures. China is one of those countries that, unexpectedly, has proposed to cut its workday. Labor culture 996. While in a large part of the West the eight -hour workday begins to be seen as a vestige of the last century and fights for the reduction of working hours, in China the culture 996 still continues: work from nine in the morning to nine o’clock at night and six days per week. Such and as they tell In ethic, that pace of work is taking Chinese society to the extreme, pulling on the soils The birth rate in a country that for years has sinned just the opposite. Chinese authorities have been trying for years Eliminate the culture of 996 of the workplace, but Without too much success. Dji has seriously proposed. According to The published by SCMP, Since the end of February something very curious is happening in DJI, the Chinese drone manufacturer. When the clock marks nine o’clock at night, a squad of human resources managers travels through the brand’s central offices in Shenzhen. Their mission is to make sure that all employees without exception leave their jobs and go home as if it were a fire drill. Instead of evacuating the building for security, employees are “guests” to leave their cubicles to meet a new rule: no one can work beyond their day. The fault is “Neijuan”. No, Neijuan It is not the name of the company’s Human Resources Manager. The term could translate to something as “involution” and, as they explain in SCMP, It refers to the need to reduce excess competition in certain areas of the economy. The measure is imposed as a New economic policy of China in which it is intended to reduce the excess of competence that makes companies in certain sectors such as The technological either Renewable energiesinvest an unnecessary amount of resources without obtaining an improvement in their profitability or in their R&D in return. Therefore, it implies outbound templates without registering a significant advance generating inefficient competition. It is something unpublished in China. Until recently, it was common to see the offices of DJI illuminated until the early hours of the morning with employees who lengthened their days until infinity. Now, the image is very different and has impacted many who have commented on social networks. The Asian media highlighted the publication of a worker surprised by the measure that commented “it was the first time they threw me from the office.” Other technological giants are adding. Although the work culture 996 has the support of prominent names of the Chinese technology industry Like Jack Mamore and more international companies such as Haier or Measure They are adding to the call of the Chinese government of limit the days of its employees. According to sources of SCMPHaier would have ordered all the staff of his headquarters to respect the breaks of two days of the weekend, while Midea has begun to demand that the workers file their departure at 6:20 p.m., instead of 9 pm.

The greatest enemy of Perovskita’s solar panels is heat. Some researchers have found a solution: titanium

by

The commercial viability of Perovskita solar panels is getting closer, thanks to the different solutions over time. However, there is still a big problem to solve to be able to install them, but a team of engineers has managed to solve using titanium. Short. Researchers from the Technological Institute of Georgia in the United States They have achieved That Perovskita’s solar cells are more stable and support high temperatures. The solution was to incorporate titanium into one of the layers. The problem. The incorporation of Perovskita panels to the market has been a challenge because they do not last long when they are exposed to high temperatures. The reason is in one of its internal layers, known as the hollow transport layer (HTL), which allows the movement of electricity within it. This layer, usually made of a material called spiro-feet, begins to crystallize and lose efficiency when the temperature exceeds 70ºC. The solution. The technique used In research is steam phase infiltration (VPI). In this process, the solar cell is exposed to a titanium gas in a low vacuum environment. This allows titanium oxide/hydroxide (Tiox) to integrate into the HTL layer of the solar cell. In this way, titanium acts as a thermal stabilizer, preventing it from crystallizing and ensuring that panel efficiency is not degraded by heat. As a result, solar cells have preserved more than 80% of their original efficiency after 200 hours of 75ºC tests. An alternative to silicon. The study of the study to continue working the Perovskita panels and not those of silicon has been for several reasons. On the one hand, a cost of costs and energy consumption because silicon cells are much more expensive than those of Perovskita. On the other hand, the study has been conducted with financing from the Office of Solar Energy Technologies of the Office of Energy Efficiency and Renewable Energy of the United States Energy Department, so alternatives have been sought for do not depend on Chinain a context of Tariff war. More solutions for Perovskitas. The American study is not the only one who is looking for alternatives in this line. An investigation in the United Kingdom has managed to go one step further developing a method that makes solar cells more resistant to external factors such as humidity, heat and physical wear. Forecasts Until now the technology developed by the American engineers group is in patent. Commercial implementation will be pending if researchers manage to find partners and the future of Solar energy in the United States.

Eggs are so expensive in the United States that there are people opting for a desperate solution: rent chickens

by

If you have bought eggs these last days, surely there is something that has caught your attention. The price has increased, 25% in some casesand curiously its price is a Good economic thermometer. An increase in the price of eggs affects sectors such as hospitality, pastry, bakery or precooked products, and in the United States escalation The price of eggs is nonsense. And given that crisis of the eggs, there are those who opt for what before it could seem crazy: the rental of chickens. Egg-gate. There are various factors that have led to this situation. One of them is long: a gradual decrease in egg productionbut the problem that has triggered the current situation has a name and surname: Aviar flu. The North American country has been suffering a serious epidemic for months that has left us as discouraging news as the first Mild infections in humans or the First pig spread. Although it is affecting more in the US, other countries, such as Spain, started the year Taking measures To stop an epidemic. 2025 complicated. The avian flu outbreak considerably affected eggs in the country because they have had to sacrifice Millions of laying hens, reducing the offer of eggs in the market and, of course, increasing their price. As if this were not enough, the crisis is not expected to be resolved soon. The United States Department of Agriculture esteem that the price climb will continue during the next months, with increases of more than 40% in the remainder of 2025. Such is the impact that there are already restaurants that begin to charge supplements in their dishes if they carry egg. Solutions. Given the needs and crises, there are those who turn on the bulb. In this case, to whom they have thought about a “And if we set up a laying chickens rental service?” One of those companies is Rent the chickn And, really, the situation is not new. It has been operational for several years And what he offered was the possibility of “renting” chickens and poultry to offer therapies in care centers for elderly or for educational purposes for classrooms. But as if it were a Diaper company in Japanwhere they have seen business is in the possibility of offering a complete package to have chickens to put the breakfast eggs. Chicknbuster. The company does not operate in all states, but in which it is present it offers a service consisting of: Portable chicken coop with two or four chickens that already put eggs and equipped with everything necessary. Sufficient food and advice on their care. And it would be, to produce already to have even a dozen eggs a week with a couple of specimens. Jenn Tompkins is the co -founder of the company and, recently, commented They are living a high season in the business. He price of renting the chickens? About 600 for the kit and two chickens, about 800 for four chickens. And the corresponding food, of course. And it also varies depending on the area and if it is more or less remote … and has a surcharge of 25 dollars per additional week. Compensate? Let’s say that the price of the dozen reaches five stable dollars (it is already at a higher price in some places, but to have a fixed amount). In that case, if they put 12 eggs a week, there are 312 eggs in those six months, united in 26 dozen. Five dollars the dozen, there are $ 130. The accounts do not come out, there is a situation that can compensate: there are establishments that exhaust cargoes in ten minutes. As if it were toilet paper or yeast in pandemicthere is messages In social networks that show that in some shops the eggs fly, so, with your chickens at home, you would not have that problem. Now, seen that there are about 600 dollars for rent for six months, perhaps what compensates is to invest first in a chicken coop and animals … and enjoy the morning eggs without the Caduque rental. Beyond all this, the amazing thing is that all this It arose 10 years ago with a night search on Google of “crazy business ideas.” Image | Rent the chickn In Xataka | In Alicante there is a city invaded by chickens. So you have prepared a plan of 26,000 euros to get rid of them

We have a problem with used wind blades. A German startup believes to have a solution: make them wood

by

At some point he had to arrive, because in the end, everything comes to an end, even the materials for renewable energy. First it was the turn of the solar panels, which now have Recycling centers. Then, it was the turn of the wind energy that their blades have found a second life in different structuresfrom mini homes even jelly beans. But so far, no one had achieved what he has achieved in the wind sector: starting from scratch with completely recyclable materials. 100% recycled. The German company Voodin Blade Technology has developed The first wind turbines made of laminated wood. This material has represented a recyclable alternative to the traditional carbon fiber, fiberglass and epoxy resin. In addition, the most curious thing is that it has greater fire resistance and a rigidity-pepper relationship similar to fiberglass, which allows you to resist all climatic conditions. As of 2026, the German company has been associated with the Indian company Senvion for install some blades of more than 50 meters In 4.2 MW turbines. The tests will be held in Europe at the end of next year and beginning of 2027. The goal. The German startup has found a rather big problem within the wind industry. While in the solar sector there are already recycling centers for photovoltaic panels, such as European photovoltaic recycling center (CERFO) In Teruel. I asked that it was around the company was: What about the wind turbines? The investigation took them to A study by the University of Cambridgewhich revealed that by the year 2050 there will be 43 million tons of shovels worldwide. The reason was none other than conventional materials are very difficult to recycle, so they reached the rolled wooden blades. This solution that is based on reuse to prevent them from ending up or are incinerated. In addition, the use of a natural material such as wood has a lower impact on the product life cycle, since it can be replaced and managed more responsible. Manufacturing. The process to get LAMINADA WOOD It goes on presses and laminating, as the name implies, wooden panels, creating resistant and durable materials. This type of wood is already used in the construction of skyscrapers and other important infrastructure, which demonstrates its reliability. Laminated wood offers a greater flexibility In the design, which allows to create longer blades and higher towers, optimizing the efficiency of the turbines by taking advantage of stronger wind currents. This advance not only provides a more ecological alternative, but also makes the production of blades more economical. In addition, in the manufacturing process eliminates the need for molds, which further reduces production costs, and makes the process more efficient and accessible. In fact, wooden blades can be up to 20% cheaper than traditional ones, according to The German company declared to Recharge. Although something if it had been recycled. While some advances have already been achieved in the recycling of traditional blades, the VOODIN BLADE TECHNOLOGY approach goes one step further. Although it should be noted that the Danish company Vestas has developed A chemical process capable of decomposing epoxy resins and then reuse in new blades, preventing them from ending in a landfill. And fire resistance? It is quite curious because they can even be replaced, but resist fire. In the first place, laminated wood can support high temperatures because being a natural material, it has a Greater self -extinguishing capacitywhich means that it is less prone to burn or spread rapidly in case of fire. In addition, advances in their treatment make it more lasting and stable in front of the fire. On the other hand, traditional materials, such as fiberglass and carbon fiber, although strong and light, do not have high fire resistance. In the end these components, together with the necessary resin to unite them, are more susceptible to decomposition and the release of toxic gases when exposed to high temperatures, which can compromise the structural safety of the turbines in a fire. The future of the big shovels, but … The German startup was news last year when installed 19.3 meters blades In Germany. Now seeks to overcome that milestone with blades of more than 50 meters in lengththe largest manufactured to date with laminated wood. However, in the field of wind energy, China continues to lead the race in large infrastructure. Recently, the Asian giant He has managed to install A Qihang wind turbine, with a 151 -meter tower and a 260 -meter diameter rotor. If mathematics does not fail, we would be talking that the length of a shovel is 130 meters, of course it is not laminated wood. And if I get more searching in the newspaper library, the discussion about the size of the wind turbines would give for an article itself. Just point out that at the moment none has surpassed the wind turbine to take advantage of the strength of the typhons with A 310 meter blade diameter. What we know so far is that laminated wooden blades could mark a before and after in wind energy, reducing costs and environmental impact. If the tests confirm its efficiency, this advance will open the way to more sustainable turbines.

We have centuries contaminating the seas with mercury. We did not expect the solution to be genetic engineering

by

There is something that have volcanic eruptions, oil combustion, waste incineration, chemical substances or gold extraction: they release mercury in the environment. A mercury that ends up deposited in the waters, transformed into methylmercury for millions of microorganisms, stored in fish and, finally, served in our houses at lunchtime. We have a problem with methylmercury. That is obvious. The problem is that it is very difficult to solve. And that is not forcing ideas in another place. What exactly is methylmercury? Mercury is already a global concern due to its persistence in the environment, its ability to bioaccumulation in ecosystems and their important adverse effects on human health. But methylmercury, the most frequent organic form in the marine environment takes the palm. None of this would be a problem if it were not because, in addition, methylmercury is the form “more toxic and the most easily absorbable For living organisms, since it is highly liposoluble and has a great capacity to fix proteins and also shows a high degree of bioaccumulation. “ Is it dangerous? Well yes. High doses of this compound They are very toxic to the central nervous system and especially “for the brain in development of the fetus and in early childhood.” It can cause “mild behavioral problems, language disorders, memory losses, vision and auditory, learning difficulties and development delays.” And we do nothing to avoid it? Yes, we have tried several approaches. In 2013, governments around the world adopted the Minamata Agreement to try to control the “anthropogenic liberations of mercury and other compounds” derivatives. In fact, in the last decade the European Food Security Authority (and its national equivalents) They have been establishing increasingly strict criteria for food with risk of exposure to these compounds. The problem is that it is not easy to control that release and, for now, we cannot do much more than reduce risks. A solution … original. Now, some Australian scientists say they have discovered a new effective way to clean the methylmercury. The Macquarie University Research Team and the Australian Csiro has managed genetically fruit flies and zebra fish to transform methylmercury into a much less harmful gas that is dispersed in the air. The team has modified the DNA of these two animals to insert variants of bacteria genes that make them create two enzymes that can convert the methylmercury into elementary mercury. In general terms, we could say that they inactivate it. It does not become harmless, but its toxicity and bioaccumulation falls very significantly. Oh really? “It still seems to me that we can use synthetic biology to convert the most harmful form of mercury and evaporate it,” Kate Tepper explainedsynthetic biologist and main author of the article. And, indeed, almost science fiction sounds. It must be said that, obviously, we talk about an investigation in the early development phases and much remains to be checked. However, it is a very interesting result. Very dangerous and very loaded with ethical issues, but very interesting for the development of the genetic engineering of the future. Another thing is that we dare to get so far.

Sending the ID to a stranger is dangerous. This new app has a free solution: put water brand

by

The DNI is a document as important as dangerous is to share it with third parties without taking concerns. Surely we have all ever faced someone, whether a person or establishment, who asks us for a copy of the ID to, for example, complete a reservation or a purchase. It is an extended practicebut not sure. The consequences can be disastrous, so it is recommended edit the document Before sending it. There are several optionsbut This tool It promises more security and put it more difficult for the IAS for the modest price of zero euros. The most interesting thing is that, although it works through the browser, there is no cloud in between. Everything works at home. His name: Saferlayer. “Hey, the copy of the ID …”. A scammer can use our ID to commit crimes (such as impersonation of identity), access to an betting house or ask for a loan in our name. Nothing good, of course. Therefore, it is important that if we are forced to share a photocopy of the DNI we do it prior edition. This type of DNI -related scams They are relatively known on the purchase and rental platforms. The lack of supply, the enormous demand and despair to find a floor can make, with the rush, let’s forget to take the necessary precautions and we will find two negative things: that the announced floor did not exist and that a total unknown has Our ID. The general recommendation is never to send a copy of the DNI or passport without editing What is the problem? Not everyone knows, wants or can use dedicated tools like Photoshop. Pixelar an image or a piece of an image It is very simple (and not as sure as it seems). Also add text or a watermark, but you have to know. Not only that, but these water marks can be edited and removed afterwards and leave the image as if nothing had happened. The solution: a dedicated tool. Carlos Sánchez, Head of Product in Real Madrid, and his “Compi de Side Projects“Guido Fioravantti, got to work after Carlos had to send a copy of his email documentation. In telephone conversation with Xataka, Carlos Sánchez explains that” you take any traditional water brand and pass it through some tools for some tools Specialized artificial intelligence, you’ll see that they take it off in seconds. What we wanted was to avoid that. “ After several tests and iterations, they found a “water mark that covers the entire document, which deceives the AI; makes it difficult to differentiate the water mark from the background image, so when you try to remove it, load it is loaded part of the document and is proof that it has been manipulated in some way. “ Copy of the original ID (above) and edited with Saferlayer (below) | Image: Saferlayer The water brand. It consists of a wave pattern with a degraded one that goes from fuchsia to green. “This has been a very proof and error process,” explains Carlos. “In that process we detected that this undemed undulating pattern, that flag effect waving, made it difficult for the AI. These color changes throughout the pattern also complicate it. In the end, we had to find the balance between whatever Very difficult to remove for AI, but also that it was readable, “he says. For Carlos, it was important that it was “evident to the person generated by the document and for whom he receives that there is a watermark that can be read, especially so that the person who receives it does not have incentives to use it for purposes Fraudulent “. This is the document edited with Saferlayer when we pass it through one of the many existing tools to eliminate the water mark | Image: Saferlayer, Xataka Everything at home. One of Saferlayer’s keys is that It works at homenothing leaves the browser. The image we are going to edit does not climb any server. This can be easily verified with the inspector of the browser itself or, simply, adding the Webapp to the home screen and putting the mobile in plane mode. We will verify that it continues to work without problem. When you upload an image, we simply have to specify the use that the copy has, for example, “Valid copy only to confirm the ABCDE hotel reservation.” Once this is done, the tool is responsible for adding the watermark. It is practically instantaneous. The tool works with all types of documents in image format (JPEG and PNG), but not with PDFs. Water brand detail | Image: Xataka A success. The tool was launched on Sunday afternoon and spread mainly Through x. It soon went viral and that can be seen in the figures. As Sánchez confirms us, “right now we are doing a water mark every nine seconds.” To the elderly, the idea of ​​the creators, their vision, is to develop a tool that allows the “total traceability of the document. That allows the individual to protect their document add a water mark, but we also have the idea of ​​covering the other part , to the company that receives the document and wants to make sure whether it is legitimate or not. ” In Carlos’s words, “we would like to evolve this to verify that the documents that have Saferlayer water mark have been manipulated in some way, or if it is the water mark as it has been generated by the tool.” “Right now we are doing a water mark every nine seconds” In that sense, Carlos tells us that a hotel in the center of Madrid has contacted them because he was “very interested in exploring tools that facilitate these processes (in reference to the new lodging record) since it generates a brutal administrative burden and makes Check-in the process more uncomfortable for customers. “According to Carlos, the hotel wanted to talk to them to see if Saferlayer could” potentially help them. “ … Read more
