It is well-known that any invention has a long way to go before becoming perfect. So do intelligent fingerprint locks.

So, what are the advantages of fingerprint locks?

First, distinguished from the traditional mechanical lock, a fingerprint lock has fancy appearance, which might be the most appealing characteristic of the fingerprint lock for people noticing it for the fist time. But this advantage may not be that attractive for ordinary families. 

Second, it is convenient for people to use the fingerprint lock. With intelligent technologies, the fingerprint lock can be opened and closed without a key while the traditional mechanical lock must be opened and closed with a key. Moreover, the key of the fingerprint lock can be changed for thousands of times. In this point, the fingerprint lock is more cost-effective than the traditional lock and is suitable for all people.

With the fingerprint lock, users are able to enter and leave the room without any keys, which saves time. Moreover, there is no need for lock users to worry about being unable to open the lock and enter their own houses if the keys are lost. Therefore, using the fingerprint lock can save both time and money. 

However, this function is not suitable for most families and is only beneficial to places with high staff turnover. For example, in urban China, there are lots of families comprised of only three members without nannies or professional cleaners. These families almost have no need to change their fingerprint passwords, but they still have to pay money for the intelligent fingerprint lock due to the function which is useless for them.

The third point is the security problem of the intelligent fingerprint lock. In general, the fingerprint lock adopts the structure with a mechanical key hole for the unexpected cases and the key hole is similar to the key hole of the cheapest traditional mechanical lock with extreme low security. It can be easily picked just like the A class pin tumbler lock. 

Except the old-style A class lock cylinder, there are new super B class lock cylinders and C class wafer tumbler lock cylinders on the current market. These two kinds of lock cylinders have not been picked until now. Therefore, it can be concluded that high-quality locks will not be picked and can ensure safety for users. Meanwhile, the cost of the high-quality mechanical lock is less than the cost of the intelligent fingerprint lock. First, the price of the high-quality C class wafer tumbler lock is only from 200 RMB to 300 RMB, which is much lower than that of the intelligent lock. Second, making duplicate keys for the lock may cost about 200 RMB, which is still cheaper than purchasing a new intelligent lock.
