• Silk ID Fingerprint Sensor
  • Face & FP huge capacity
  • Access control

G3-H is a multi-biometric identification terminal which features ZKTeco’s innovation Silk ID fingerprint sensor technology. With the world’s cutting-edge 3D Neuron Fingerprint Algorithm, it precisely authenticates dry, wet, or rough fingerprints efficiently and accurately. Infrared technology enables the device to function automatically when fingerprints are detected. With the latest facial algorithm, it supports color photos detection and prevents repeated face registration. G3-H also comes with hardware promoted, it supports huge capacity of facial and fingerprint users, maximum up to 50,000 users and 1,000,000 transactions.

  • Modern design and interactive user interface
  • Revolutionary Silk ID fingerprint sensor
  • Multiple verification modes: face/fingerprint/card/password
  • Outstanding Performance With Dry, Wet and Rough Fingers
  • Simple Management & Scalability
