In the global fingerprint recognition chip industry, the successful commercialization of technology serves as the ultimate measure of its advancement. Currently, only two companies worldwide have successfully brought glass-based fingerprint recognition chips to market, and Shenzhen-based Xingqihang Technology Co., Ltd. is one of them. This achievement alone attests to the maturity and leadership of its technological approach. So, what fundamental advantages does Xingqihang’s chosen path—replacing traditional silicon-based chips with glass-based ones—actually offer? The value lies primarily in three core dimensions: cost, security, and lifespan.

I. Cost Restructuring: Achieving a Breakthrough Reduction of Approximately 75%

The revolutionary aspect of Xinqihang’s technology lies in its direct integration of the fingerprint chip’s sensor, controller, and even the entire circuit system onto a glass substrate. This process innovation eliminates the need for the expensive semiconductor wafers that traditional silicon-based chips rely on as a carrier. There is an order-of-magnitude difference in raw material costs between glass and wafers, enabling Xinquhang’s glass-based chips to achieve a total cost of approximately one-quarter that of traditional silicon-based solutions. This not only provides end products with a highly competitive price advantage but also clears a key economic barrier to widespread adoption amid the trend toward “domestic substitution.”

II. A Quantum Leap in Security: From “Pattern Recognition” to “Liveness Verification”

The superior light transmittance of glass substrates—particularly their ability to transmit infrared light—is unmatched by silicon-based materials. CoreQihang has astutely leveraged this physical property to innovatively integrate an active infrared liveness detection system into the chip.

Through built-in infrared emitters and receivers, this system can imperceptibly detect the blood oxygen characteristics of subcutaneous tissue the moment a user presses the sensor. The blood oxygen saturation of a real human finger typically exceeds 95%, and it exhibits specific absorption and reflection patterns for infrared light; counterfeit items such as silicone fingerprints, however, completely lack this biometric characteristic. Consequently, this technology effectively blocks fake fingerprint attacks at the physical level, elevating the security defense from two-dimensional image matching to three-dimensional biometric verification, thereby achieving a fundamental leap in anti-counterfeiting capabilities.

III. Doubled Lifespan: A Durability Revolution from 100,000 to 1 Million Cycles

Durability is a key indicator of chip reliability and product quality. Traditional capacitive silicon-based chips, limited by material fatigue and structural constraints, typically have a press cycle life of around 100,000 times, corresponding to one to two years of intensive use. In contrast, CoreQiHang’s glass-based chips achieve an order-of-magnitude leap in service life thanks to the inherent robustness of glass and the enhanced reliability provided by their monolithic integrated structure. Rigorous testing has shown that their press cycle life easily exceeds 1 million cycles and can consistently pass durability tests exceeding 3 million cycles—reaching ten to several dozen times that of conventional silicon-based solutions. This makes them fully capable of withstanding various high-frequency, demanding commercial and government applications, significantly reducing long-term maintenance costs and the risk of device failure.

In summary, Xingqihang’s glass-based fingerprint chip is not merely a simple material substitution, but a comprehensive solution that systematically redefines product cost structures, security logic, and durability standards through fundamental technological innovation. It demonstrates that on the path to technological excellence, Chinese enterprises are not only capable of keeping pace with the cutting edge but also have the ability to define new performance benchmarks and reshape the market landscape through unique technological approaches.
