• G3 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 fake face detection.
