Beijing, May 21, 2024 — A new era of smart travel has officially begun.

This innovation is powered by GRG Intelligent, the project's general contractor and total solution provider.
Simplifying Complexity: Technology Empowering Mobility
Tap Into the Future – With Just a Wave of Your Hand
Designed for seamless travel, the palm scanning system allows passengers to enter and exit stations simply by raising their hand. Using advanced dual-mode biometric technology—palm print and palm vein recognition—this solution offers a contactless, secure, and convenient alternative to traditional tickets or facial recognition.
Unlike face recognition, this method ensures user control and privacy, requiring a conscious palm scan at the gate. Data security is a top priority, with dedicated encryption and secure communication channels safeguarding passenger information.
Passengers scan their palm prints to pass through the gate
Fast Setup, Effortless Commute
Getting started is easy:
Ride hands-free – simply scan your palm at gates marked with a ring symbol. When recognized, the ring lights up green and the gate opens.
Even if your phone is out of battery or you’ve forgotten your card, your palm is your pass. It’s hygienic, fast, and future-ready.
Smart Travel Backed by Innovation
GRG Intelligent, a subsidiary of GRG Group, is at the forefront of driving AI-powered transportation solutions. With continued investment in emerging technologies, GRG is reshaping urban mobility through the fusion of AI and digital infrastructure.
