People who are already familiar with biotechnology such as face-brushing payment and iris recognition in China will surely be curious about the differences between them. It is said that it is faster than brush face payment and iris payment, and it can complete identity recognition and payment in about one second. In the test, it shows the fastest speed of .3 seconds. The principle is based on the reaction of hemoglobin in blood vessels under people's palm prints to infrared rays, which is often unique, more accurate and not easy to be faked. If vital signs are lost, it will fail within three minutes, which is safer than brushing your face. At present, it is used in unmanned stores in Seattle, USA, which is more user-friendly and convenient than the previous payment that needs to automatically generate QR codes.
In the unmanned stores launched in the United States before, the final payment list was displayed according to the camera and sensor moving with the customer's footsteps, and the final price was settled according to the QR code on each product during payment. In this process, errors about quantity, such as missing a QR code, were prone to occur, while the wave payment system solved this problem well, simplified the final payment steps and made the shopping process of unmanned stores smoother. Compared with the Chinese people's willingness to try new things in the payment system, the American people actually tend to be conservative in the payment method. If Amazon wants to promote the wave payment system, it needs to give customers the same subsidies as traditional credit card payment.
In fact, the public will question why it is difficult to promote the credit card model and payment methods other than cash in the United States, which are obviously so easy to use and convenient. In fact, in addition to the American people's attention to privacy, traditional credit card institutions will give a certain percentage of subsidies, even if the credit card handling fee is not cheap.
judging from the American people's resistance to face brushing and fingerprint iris payment, waving payment seems to be a good solution to their concerns. Amazon members only need to bind the card to the id in their hands.
Amazon, whose market value exceeds the sum of Alibaba and Tencent, obviously has surpassing ambitions, so it is more cautious and thoughtful in research and development. Of course, some people doubt whether it is really convenient to pay by waving when customers have two hands full of goods.
