WeChat unveils palm print-based payment system in China

WeChat Pay has unveiled a palm print-based feature that enables users to make payments using their palm prints on face recognition devices.

Powered by Weixin Pay (微信支付), the feature requires users to link their personal WeChat accounts to the device and register their palm prints. When making a purchase, they can place their hand over the scanning area of the payment device, enhancing the user experience by offering a unique payment transaction.

The feature is now accessible at every station on the Daxing International Airport Line (北京大興國際機場) of the Beijing subway system. Passengers may swipe their palm across a scanner to enter and exit the subway, enabling them to access subway trains without the need for their phones or cash.

According to multiple Chinese reports such as Gizmochina, the palm print-based feature combines surface-level palm prints and unique vein patterns for transaction authentication. Users can authenticate their transactions by scanning and uploading their palm prints to a ticket machine. They can then link these scanned prints to their personal phone number and ID through the WeChat mini programme, enabling them to initiate payments effortlessly. This solution leverages both palm prints and vein patterns, which enhances security and convenience in the payment ecosystem.

The technology is able to adapt to various environmental lighting conditions, ensuring reliable performance regardless of the lighting situation. Furthermore, it can handle the physiological variations in palm prints among different individuals, quickly identifying user patterns even when users present their hands in different positions or orientations.
