Beijing officially launched China’s first palm payment metro line on the Daxing Airport Line, marking a new chapter in smart urban mobility. We provided the end-to-end solution — from system design and deployment to implementation. This milestone project transforms commuter experiences by introducing palm-scanning entry, combining biometric convenience, security, and technological innovation.
The palm-scanning system integrates palm print and vein recognition technologies, offering a contactless, card-free, and high-security ticketing experience. It minimizes physical interaction and ensures user privacy through dedicated data encryption and secure communication channels, establishing a benchmark for safe and intelligent travel.

Technology makes travel easier and smarter.
Palm-Scan Access: No Cards or Phones Required
Forgot your card? Phone out of battery? No problem! Simply extend your palm for instant identity verification and the system will process the payment, allowing for “entry upon arrival.”
Dual Recognition Technology for Enhanced Security
Palm print + palm vein dual-mode technology delivers fast recognition and low error rates. Encrypted communication and dedicated pathways ensure comprehensive user privacy protection.
One-Click Registration for Easy Access
Enroll your palm print at a self-service ticket machine and authorize via the “Beijing Metro Palm Vein Payment” WeChat mini-program to activate your palm-scan travel experience—fully self-service, convenient, and efficient.
Contactless Access, Hygienic and Safe
No need to touch devices, minimizing the risk of cross-contamination and meeting modern urban public health standards.
