It is worth reminding that many users think that the key is the least important and often leave it at home. In fact, the keys should be placed in a fixed place outside the home, such as an office or a parent's home, in case of emergency. Although the fingerprint lock has stable performance, it does not rule out that sometimes its electronic components fail. I have experienced that after scanning the fingerprint or swiping the card, the fingerprint lock does not respond. At this time, only the key can be used to open the door.
In use, some fingerprint locks will also have a quick response in summer, a quick opening, and a slow recognition of fingerprints in winter. According to industry insiders, this is mainly caused by changes in temperature and humidity. At this point you can sigh at your finger and then scan your fingerprint.
Most people who like fingerprint locks are young people. Many people find that the price of fingerprint locks in the online sales channel is several hundred yuan cheaper than the physical storefront. If the online sales channel does not have offline installation support, it is not recommended to purchase through the network. Because the installation of the fingerprint lock requires local changes to the security door. In order to promote sales, some online merchants often confuse consumers to just install the security door to install, in fact it is not so simple. And through physical store purchase, after-sales service is also more secure. When you are defending your rights online, you need to remove the fingerprint locks and mail replacement. The cost is a few hundred yuan. It is not enough to hire people to disassemble and worry.
