Simply pay for the purchase with a scan of your own palm – this is already possible in many branches of the Amazon chain Whole Foods in the USA. The group wants to bring the function to all stores by the end of the year. We explain how the Amazon One payment function works.
As early as 2020, Amazon introduced palm payment in its Whole Foods stores. Since then, the group has introduced the Amazon One payment function in more than 200 locations. According to the company, the group has registered more than three million uses since it was introduced.
But the next milestone should follow by the end of the year. Because by then, Amazon One should be available in all of the chain’s US markets – i.e. in more than 500 stores, as the group has announced.
How does Amazon One work?
Amazon One is a form of biometric authentication. Similar to Apple’s Face ID, it works contactless. However, it does not scan your facial features, but the structure of your hand.
But the scanner not only registers the lines in your palm. Amazon One also scans the underlying vein pattern. From this, Amazon one creates the palm signature, which you can then use to pay.
According to Amazon, this doesn’t work based on simple pictorial representations of your palm. Rather, Amazon One creates a unique numeric vector representation on which the palm signature is based.
Registration for Amazon One
A credit or debit card is required to use Amazon One. For this purpose, Amazon has entered into partnerships with American Express, MasterCard and Visa as well as major US banks.
Registration works either online by entering your Amazon account and cell phone number – or in a shop with access to Amazon One.
Users who register online can scan their palm on their next visit and thus create their palm signature. If they are members of Amazon Prime, this is linked directly to Amazon One for discounts, for example.
Where does Amazon store the data?
Amazon chose palm recognition because it is more confidential than other biometric recognition systems. For example, a person’s identity cannot be recognized from the palm of their hand.
The group stores the data for Amazon One in its in-house cloud computing system AWS.
When you scan your palm, the palm and vein images are instantly encrypted and sent to a highly secure zone in the AWS Cloud built specifically for Amazon One.
In addition, Amazon One has a detection function for manipulation attempts. If the device detects such an attempt, it automatically renders itself unusable.
