“I’ve got something to do. Could you clock in for me today? I’ll treat you to a bubble tea later.”—Clocking in on behalf of others has become a persistent problem in corporate attendance management. Fake fingerprints can be made for as little as a few dozen yuan; with just two steps—imprinting and molding—ordinary time clocks can be bypassed. Traditional time clocks only compare fingerprint features and cannot distinguish between real and fake fingerprints, making it nearly impossible to prevent others from clocking in on your behalf.

Why Do Traditional Solutions Fail?

Optical sensors are fooled by silicone films, while capacitive sensors are mimicked by conductive adhesives. Essentially, these methods rely on “image matching” and do not verify whether the object pressed against the sensor is an actual finger. Only technology capable of detecting vital signs can provide effective protection.

Xinqihang’s Solution: From “Feature Recognition” to “Vital Sign Recognition”

Xinqihang’s glass-based infrared fingerprint chip upgrades attendance technology from “comparing feature points” to “detecting vital signs.” When a finger is pressed against the sensor, the chip emits infrared light to detect subcutaneous vital signs (such as blood flow). Fake fingerprints (made of silicone, conductive adhesive, etc.) lack vital signs and cannot pass verification. By comprehensively analyzing both infrared reflection patterns and fingerprint characteristics, the system can effectively distinguish between genuine and counterfeit fingerprints.

Reliability Provided by the Glass Substrate

The glass substrate features low dielectric loss and minimal parasitic effects, resulting in reduced signal interference and a higher image signal-to-noise ratio. With a surface hardness exceeding 5H and ESD protection of ±8 kV (contact) / ±15 kV (air), it boasts a lifespan of one million presses, easily handling frequent use in enterprise environments. It accurately recognizes touches from dry or wet fingers, as well as cracked or dirty surfaces, and remains responsive even in cold winter conditions.

Authoritative Certifications

The product complies with the GA/T 1011—2012 national standard and has been certified by both the Ministry of Public Security and Microsoft.

From “proxy clock-ins” to “authentic attendance,” Xinquihang uses infrared detection technology to ensure every fingerprint is genuine and reliable.
