G4 [QR]
G4 [QR]
  • Available with QR code scanner
  • Supports mask detection
  • Supports OSDP

G4[QR] is a multi-biometric identification terminal that features ZKTeco’s innovative Enhanced Visible Light Facial Recognition and QR Code Scanning technology. The device with the latest technologies can automatically perform recognition at a distance from 0.5m to 3m when a face is detected. It delivers higher recognition quality in speed and accuracy than other terminals using near-infrared facial recognition technology. With the applied Deep Learning algorithm, pose angle tolerance and anti-spoofing performance has been greatly enhanced against various environmental conditions and different types of spoofing attacks.

G4[QR] is equipped with an excellent mini QR code reader, which supports QR code, PDF417, Data Matrix, MicroPDF417, Aztec, and so on. And it can scan the T&A/A&C QR code on the ZKBioSecurity Mobile App.

In addition to the optional ID and IC card modules, G4[QR] can also perfectly support ELATEC card modules and can support 125kHz, 134.2kHz, and 13.56MHz RFID cards without changing the card module.

If the function mentioned above cannot meet customers' needs, we can provide an EDK embedded development kit and adjustment tools. Based on our robust and stable platform, the client's R&D team can quickly develop, integrate, and debug the entire embedded system to get more scalability.
