In addition to the current automated method of using smartphone codes to shop in Amazon Go stores, Amazon has introduced Amazon One, a new biometric device that enables customers to pay by placing their hand above a sensor. This feature recognizes the palm and connects it to the customer’s credit card, allowing automatic payment.

To set up the  service, customers will initially have to insert their credit card in the Amazon One device and place their palm above it to be scanned. The customer can choose to add a second palm print as well. The camera in the device takes multiple photographs of the palm, capturing minute details for accurate identification. Utilizing computer vision technology in real-time, the Amazon One device creates a unique palm signature. 

Thereafter, the customer will be able to enter and shop at all stores with the Amazon One device, by simply using their palm. Amazon claims the palm images will be encrypted and stored online securely.

Currently piloting at two Amazon Go stores in Seattle, this new tech is expected to be implemented in other Amazon Go stores in Seattle, New York, San Francisco, and Chicago.

Amazon plans to expand this feature to third-party retailers such as stadiums and offices in the future.
