Problems solved by technology

In daily life, the most common is the mechanical lock, the structure of the mechanical lock is relatively simple, and it is easy to use, and the price is relatively cheap compared to other functional locks, but it also has certain disadvantages: low security, easy to lose, And after being lost, whoever picks it up can use the key to open the lock, which is easy to copy, so the safety of the mechanical lock during use cannot be guaranteed
