Say goodbye to cash, cards and transfers: Now you will pay with the palm of your hand

Can you imagine you can pay for your groceries or public transportation tickets with the palm of your hand? This is already a reality thanks to biometric technology. Our hands store unique information that can be connected to your financial data stored in the cloud so that the purchase can be processed correctly.

amazon One Palm Payment is a biometric payment system developed by amazonwhich allows users to make payments or authenticate to systems and services by scanning their palm.

This system uses advanced imaging technology to identify the unique characteristics of each individual’s palm, including lines and patterns, providing a safe and convenient form of contactless verification.

Users register their palm once and can then use it to make payments at select stores such as Whole Food, the American supermarket chain.

To pay by hand using the Amazon One Palm Payment system, users must follow an initial registration process and will then be able to make payments easily:

– Initial registration:

1. The user visits an Amazon One terminal at a participating establishment.
2. A credit card is entered to link to the Amazon One payment system.
3. The terminal then asks the user to position their hand on the device to scan the palm. This process captures the unique structure of the palm, creating a unique biometric identifier.
4. The system requests to scan both palms for convenience in future payments, although this is optional.
5. Once registration is complete, the user’s Amazon One account is linked to their palm and the credit card entered.

– Make a payment:

1. When arriving at the checkout of an establishment with support for Amazon One Palm Payment, the user simply places their hand on the Amazon One reader.
2. The system quickly identifies the biometric signature of the palm and proceeds to charge the associated credit card during registration.
3. The process is quick and does not require physical contact with the terminal, which adds an additional layer of hygiene and security.
4. Once the transaction is confirmed, payment is completed and the user can continue with their day.

This payment method is designed to offer a secure, convenient and fast alternative to traditional payment methods. Its use, however, It is limited to establishments that have the necessary technology to support the Amazon One Palm Payment system.

Tencent, a technology company, has developed a biometric payment method that uses palm scanning, connecting with mobile payment platform WeChat Pay to carry out transactions.

According to the developers, this has already been implemented in a series of stores in Shenzhen, and its use is quite intuitive: the buyer simply has to slide his palm over a device that has a biometric recognition screen.

Then, The device automatically recognizes the person who has previously registered and makes the purchase.

According to an analysis by Goode Intelligence, the global biometric payment systems market is expected to exceed 3 billion users and reach a value close to US$5.8 trillion by 2026.

Edward Santow, who is an industrial professor of responsible technology at the University of Technology Sydney, has noted that while many users have adopted biometric payments to reduce their dependence on credit cards and mobile devices, security concerns and privacy protection is still considerable.

Likewise, Santow warned about the risk that the mass collection of personal data could be attractive to cybercriminals. As a large amount of personal information accumulates, it creates an attraction for online criminalshe explained to CNN.
