Amazon is vigorously promoting the "pay by hand" function, scanning the palm of the hand for payment in a second.

CTOnews.com8, March 10 (Xinhua)-- Amazon launched a palm scan payment technology called Amazon One in 2020, which allows users to pay by scanning the palm directly. This technology has been used in some stores in the United States, and now Amazon is expanding the technology to 65 whole food stores in California, according to The Verge, which is Amazon's largest promotion to date.

The technology, known as Amazon One, allows customers to use Amazon One self-service machines to take photos and add palm information in stores that support it, as well as mobile phone numbers and debit cards (credit cards). After the setup is complete, you can take the item to the front desk to check out. You don't need to take out your wallet or cell phone. You just need to hover your hand over the device to complete the payment and leave.

Amazon says everyone's palms are unique, and even one person's two palms are different. At the same time, palm photos taken on the Amazon One self-service machine will not be stored locally, they will be encrypted and sent to the Amazon One dedicated cloud server to generate recognizable palm features on the cloud server.

CTOnews.com learned that Amazon One has been applied to 70 stores in many places in the United States, and Amazon is expanding in other places. At the same time, Amazon is also actively promoting the application of this technology in other areas, such as access control.
