Human skin consists of three parts: the epidermis, the dermis, and the subcutaneous tissue. Fingerprints are raised lines on the epidermis. Due to human genetic characteristics. Although fingerprints are available to everyone, they are all different. Reaching out and observing carefully, you can find that there are several types of small fingerprints: concentric circles or spiral lines, which look like whirlpools in the water, called bucket patterns; some lines are open on one side. Like a cockroach, it is called a cocoon; some patterns are like a bow, called a bow line. In addition to the different shapes of fingerprints, the number and length of lines vary. It is said that no two fingerprints have been found in the same person. The fingerprints began to appear in the third or fourth month of the fetus and were formed in about six months. When a baby grows up, the fingerprint is only enlarged and thickened, and its pattern remains unchanged.
Fingerprints are hard to find in the world, so fingerprint recognition technology has been applied to safes. It is confidential and easy to use. However, the opponent's dry humidity requirements are strict! The recognition of the position of the finger is also relatively precise, so the fingerprint safe is chosen to purchase a well-known brand as far as possible, the performance is stable, and the recognition rate is high.
Many companies with safes still have stolen incidents and scrutinize the reasons. It is found that the factors that lead to the theft of safes are often hidden in the password safes. 1. There are many people who use safes and are miscellaneous. , Poor confidentiality, easy to cause password leaks and financial losses; 2. There are many financial management personnel, that the password is not stolen in the safe set up a password, but I do not know the security of the password setting also directly affects the security of the security guards, The password is easy for people to see through and break through the safe easily. 3. The password of the safe should not be fixed. For example, when the cashier moves, the safekeeping personnel leave, and the property with high storage level should also change the password regularly; 4. The password after leaving the factory is not Changes, or the frequent redeployment of financial management personnel, often open passwords in the case of multiple people, are likely to cause password leaks, but often change, and finally even do not remember which one is your password.
In response to the above hidden troubles, many companies have taken the lead in adopting advanced fingerprint technology to completely solve the defects of the loss and forgetting of traditional keys and passwords, and ensure the safety and reliability of the property! There are a lot of brands that use fingerprinting now, but they are basically not their mainstream products.
