Coming home late at night, your fingerprint isn’t recognized after three tries, so you have to dig out your keys; while on a business trip, you suddenly receive an alert on your phone saying “an abnormal attempt was made to open the door lock”; a newly installed door lock starts responding sluggishly after just six months…

The root cause of these frustrations often lies not in the lock itself, but in the fingerprint chip hidden inside it.

If we compare a smart door lock to a person, the chip is its heart. If the heart is weak, the whole body suffers. Today, let’s discuss why we can’t settle for less when it comes to this “heart.”

Pain Point 1: Unreliable Fingerprint Recognition

“It won’t recognize dry hands, nor wet ones—the elderly and children are often locked out.”

Ordinary silicon-based chips are extremely sensitive to finger conditions and have limited signal capture capabilities. Xingqihang’s glass-based solution replaces silicon with glass as the substrate, resulting in less signal interference and clearer images. It can recognize dry, wet, cracked, or slightly dirty fingers, with a recognition rate of 95% even in challenging scenarios involving the elderly and children. It’s not that there’s something wrong with your hand—it’s that the chip you’ve encountered isn’t good enough.

Pain Point 2: Unlocking with Fake Fingerprints

Some people use gel to replicate fingerprints—for as little as 50 yuan, they can fool ordinary door locks.

Why? Because ordinary chips only recognize fingerprint patterns, not whether the finger is alive. Xinqihang’s exclusive live-detection technology doesn’t look at patterns—it detects blood flow and skin electrical signals. Gel? No blood flow—rejected. Tape? No electrical signal—rejected. Metal? Conductive but lifeless—rejected. This technology is backed by three major certifications from China’s Ministry of Public Security, as well as PBI-PIV certification from the U.S. and Microsoft certification. Thieves can copy your fingerprint, but they can’t copy your life.

Pain Point 3: Short Lifespan

Standard chips have a lifespan of approximately 100,000 presses, but in actual use, they begin to respond sluggishly after just one or two years.

Xinqihang’s glass-based chips have a lifespan of 1 million presses—10 times that of standard solutions. The glass material is stable and corrosion-resistant, while the redundant circuit design ensures long-term accuracy. They withstand temperatures ranging from -40°C to 85°C and are resistant to corrosion from sweat and alcohol.

For door lock manufacturers, choosing Xinquhang means: reduced after-sales service, higher product premiums, controllable costs (total cost is approximately one-fourth that of traditional solutions), and rapid response from a local team.

As the first line of defense for your home, it deserves the best “heart.”
