With the continuous improvement of living standards and the development of technology, we have higher and higher requirements for the safety index of door locks. People have gradually evolved from the ancient bolts to the current fingerprint password locks and face recognition locks.
The rise of Capacitive Fingerprint Scanner has changed people's lifestyles and bid farewell to the era of looking for keys every time they go out. The Capacitive Fingerprint Scanner on the market are mixed. I don't know what aspects to grasp a Fingerprint Scanner. Fingerprint Scanner manufacturers have summarized some experiences for reference.
There are two main types of fingerprint heads on the market now, one is a peninsula fingerprint head and the other is an optical fingerprint head. From the perspective of security, if the economy allows, it is better to choose a peninsula fingerprint head, because the fingerprint is not easy to be copied using live fingerprint technology. Optical fingerprint heads are more wear-resistant and relatively cheap, but they are not safe, easy to be copied, and have poorer recognition capabilities.
There are two main materials for lock bodies on the market now, one is stainless steel and the other is zinc alloy. Stainless steel has a higher melting point, is relatively hard, and has poor plasticity, making it difficult to make a more exquisite appearance. Except for the lock tongue which is made of stainless steel, others will choose zinc alloy with strong plasticity as a substitute, because this material has good flexibility in processing and manufacturing, and its performance in use is no worse than zinc alloy.
