A U.S. supermarket chain is embracing palm payment technology. That's right: instead of using a card, cash, smartphone, Pix or transfer, customers at Whole Foods stores simply place their hand over a sensor.
By the end of 2023, the chain's more than 500 stores will have implemented the Amazon One palm recognition service. The mechanism analyzes features such as vein patterns, palm lines, reliefs and bumps. Like fingerprints, each person's palm signature is unique.
To sign up for the new system, Whole Foods customers have to register with their debit or credit card information, phone number and Amazon account. According to the company, the process takes about 1 minute.
They can then use the hand to pay bills, join loyalty programs and get discounts, among other things.
Why palm biometrics?
According to Amazon, palm recognition biometrics were chosen because they are secure and more private. After all, you can't identify someone just by looking at their palm.
In addition, using it requires an intentional gesture, as the user must place his or her hand on the device. This is the opposite of what can happen with facial biometrics, for example, which can unlock a smartphone without the person being interested.
Another advantage is that identification is contactless, unlike the palm readers used by some banks. All you have to do is place your hand on the device for a few seconds and you don't have to touch it.
Will this trend come here?
