The silicon-based fingerprint chip market has long been a red ocean. Manufacturers are crammed onto the same path, competing on price and production capacity, while technology becomes increasingly homogeneous and profit margins continue to shrink. As patent barriers grow ever higher, the space for innovation is constantly being eroded—and in the end, no one can truly break through.

Xinqihang chose to break away from the old race track and was the first to pivot toward glass-based X technology. This move was not about catching up, but about changing lanes; it was not about refinement, but about reconstruction.

[Why Glass-Based?]

Silicon-based fingerprint chips have three major shortcomings, all of which glass-based chips can effectively address:

1. Significant signal interference: Silicon is a semiconductor with inherent parasitic capacitance, which easily introduces noise when capturing weak fingerprint signals, resulting in a low signal-to-noise ratio. Glass is an insulator with a stable dielectric constant and minimal parasitic effects, producing purer signals and clearer images.

2. Inability to support infrared liveness detection: Silicon is opaque and cannot allow near-infrared light to pass through and receive reflected signals. Glass has high light transmittance, making infrared liveness detection possible—by detecting subcutaneous blood oxygen saturation (≥95% for living individuals) to distinguish genuine from fake fingerprints, rendering fake fingerprints and severed fingers ineffective.

3. Poor durability: Silicon-based sensors have a surface hardness of approximately 3H, making them prone to wear and tear; image quality degrades after hundreds of thousands of presses. Glass-based sensors have a surface hardness greater than 5H; they remain clear even after millions of presses and are temperature-resistant (-40°C to 85°C) and anti-static (±15 kV).

4. FBI FAP60 certification, Microsoft certification, and certification by the Ministry of Public Security, with over 180 patents. From domestic customs to ports in Southeast Asia, Xinquhang has been successfully implemented and validated.

The breakthrough in glass-based technology is not merely a strategic choice for CoreSail; it also symbolizes the shift of China’s domestic chip industry from “catching up” to “changing lanes.” True advancement lies not in running faster, but in taking a different path. From silicon-based to glass-based, from “recognizing patterns” to “recognizing life”—China’s chips are not merely about substitution, but about leading the way.
