Palm Payment Unlocks a New Scenario: PetroChina Gas Stations

Recently, WeChat palm devices with hardware provided by DEPTRUM went live at PetroChina gas stations in Chongqing, Tianjin and Hunan. This novel payment method turns a user's palm into their membership card and fuel card, greatly simplifying the refueling payment process and bringing the gas-station scenario into a new era of palm payment.

The palm-refueling service jointly launched by WeChat Pay and PetroChina is both an innovation in payment methods and a new expansion of smart payment scenarios. Even without a phone or fuel card, users can easily complete refueling payment — an organic combination of convenience and innovation that fully embodies the idea of technology serving life.

The WeChat palm devices used in the PetroChina palm-refueling service carry DEPTRUM's dual-modal palm camera, responsible for palm-scanning imaging and image processing, significantly improving scanning efficiency and ensuring the accuracy and security of palm payment.

The palm-refueling service uses dual-modal verification of “palm print and palm vein.” It has passed strict certification by the Third Research Institute of the Ministry of Public Security and the National Financial Technology Evaluation Center (NFEC), guaranteeing high recognition accuracy while greatly optimizing the payment experience and making payment more reassuring.

The WeChat palm device offers a wide scanning zone and supports multi-angle palm recognition, verifying the user's palm quickly from any angle — reducing learning cost and improving payment efficiency. Especially in the queuing congestion of gas stations, palm payment does not depend on network or phone and has no behavioral constraints; extending a palm completes refueling payment, effectively relieving queuing and weak-signal pain points.

The palm device is also low-cost: a single device completes both palm interaction and verification, further reducing hardware cost. Meanwhile, the compact device gives palm payment access to more scenarios, letting more users experience this convenient and easy-to-use palm technology.

Currently, WeChat palm devices have landed across transportation, sports, campus, retail, dining, office and shared-charging scenarios, bringing users a brand-new payment option and integrating technology into daily life, creating a more novel and fashionable way of living.

The adoption of the palm-refueling service unlocks yet another new scenario for palm-scanning technology. As palm payment continues to spread, payment methods will become more diverse, convenient and secure — improving user payment experience and further promoting the intelligent and digital innovation of various scenarios. DEPTRUM will continue to rely on 3D vision, biometrics and AI technology to truly empower offline scenarios and serve daily life.
