Now on the market are mainly: mechanical passwords, electronic passwords (also points indicator and LCD display), card, fingerprint locks. With the popularization of electronic passwords and the improvement of performance stability, safes equipped with electronic code locks have become the main force on the market. IC card and fingerprint lock also have a certain market, the following analysis of the different types of passwords their advantages and disadvantages:
1, mechanical password is relatively stable, durable, and does not require power. However, the operating method is slow, inconvenient, and requires a professional to change the password.
2. The electronic password has the advantages of quick operation, simple and random change of password. Although the price of electronic code locks has dropped over the past few years, the quality has also improved, but because of its complexity, its stability and durability are inferior to those of mechanical codes.
3, card locks can use their own bank card to open the safe door, the structure of sophisticated precision, performance is more superior, but the IC card requirements are relatively high If you put a piece of strong magnetic things, it is not easy to use, easy to mistake .
4. Fingerprints It is difficult to find the same fingerprint in this world. Therefore, the fingerprint recognition technology is applied to the safe. The confidentiality is strong and easy to use. However, the opponent's dry humidity requirements are strict! The recognition of the position of the finger is also relatively rigid! Even if it is the same finger, if the position before and after the opening is different, it may recognize the failure!
