Safes with electronic lock

Electronic

— as the name implies, electronics is responsible for opening/closing such a lock, and the key is a numerical cipher entered from the keyboard. Actually, the use of the cipher determines the main advantages and disadvantages of this option. Electronic locks do not require a separate key, at the same time, the cipher held in memory can be forgotten, and the one written on paper or other media can be lost or compromised by an attacker. It should be noted that electronic locks are similar in principle to mechanical combination locks, but they have a number of practical advantages: in particular, entering numbers from the keyboard is more convenient, the numerical combination can be easily changed, the design often provides a display for input control, etc.
