The door lock is a very important thing for us and the first barrier to protect our safety. With the continuous progress of technology, many houses are now equipped with fingerprint locks. You can enter and leave without a key, which is more convenient.

But there are also many people who do not believe in the security of fingerprint locks. Fingerprint locks are still slowly popularized in people's lives. After all, every new home needs to change locks, so people will wander between traditional locks and fingerprint locks. Do you want to install fingerprint locks when changing locks at the entrance door? Teacher Fu said it before he understood that safety is more secure!

Later, we learned that the fingerprint lock is still very practical, so it can be gradually popularized by word of mouth. There are generally two types of fingerprint lock on the market, one is optical fingerprint lock, the other is semiconductor fingerprint lock. Generally, the optical fingerprint lock has a long service life, is relatively cheap, and is very wear-resistant, but its fingerprint sensing is relatively poor, so many people think it is not very sensitive.

There is also a semiconductor fingerprint lock, which is relatively more advanced, but also has advantages and disadvantages. The most noteworthy thing is that its unlocking function is very sensitive, and it can be used to unlock directly at ordinary times. The fingerprint identification function is still very fast, and it also has the function of releasing forgeries, but it is not very wear-resistant, so the service life is not so long, and the price is relatively higher.
