1 Overview
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 have been greatly enhanced against various environment 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.
