Today's market competition is becoming more and more severe. Enterprises are trying their best to create their own unique advantages in order to attract consumers. However, not all the advantages created can give products a icing on the cake, but some of them have a feeling of being overwhelming.

This phenomenon often occurs in fingerprint locks. In terms of fingerprint locks, in addition to basic functions, there are dozens of other auxiliary functions, large and small, which can be confusing and even misleading consumers. Fingerprint locks, which are high-tech products, rely mainly on electronic technology and biometrics. The simpler the environment in which these technologies are located, the better. Conversely, the more auxiliary functions, the more likely it is to reduce the stability of the main functions. Therefore, the function does not need to be excessive when selecting a fingerprint lock. Mr. Yan, the person in charge of the Dirty Fingerprint Lock Research Center, said.

Which features are fingerprint locks more useful? The reporter visited a number of shops that operate fingerprint locks, summarizing the following functions:

First, the fingerprint lock is turned on (must function) As a fingerprint lock, first of all, it is necessary to have a fingerprint opening function. It is understood that fingerprints on the market generally use optical fingerprinting methods, and a few use semiconductors. Semiconductor acquisition technology is vulnerable to static electricity, sweat, dirt, and finger wear. It has insufficient stability, wear resistance, and short life. It is also used in the field of fingerprint locks. Due to the multi-angle acquisition, optical acquisition can achieve the best accuracy, clear fingerprint image, stable identification, and effectively improve the instability of semiconductor acquisition. Therefore, it is widely used in fingerprint locks.

Second, the key to open (must function) Many consumers will think that the keys are open to the cottage products. However, the actual situation is exactly the opposite. According to state regulations, fingerprint locks must have a key opening function to be shipped from the factory. This is mainly due to safety considerations. Fingerprint locks are electronic products after all, and electronic products will have business trips or no electricity. In order to prevent fires or other disasters from damaging electronic circuits and cause people to endanger the situation, the state mandatory fingerprint lock must be equipped with a key opening function. Fingerprint locks without the key opening function are not qualified.

Third, information management functions (must function) The information management functions mentioned here are: add / modify / delete user information, user information, including fingerprint information, use information. When a customer uses one of these features, other features are not affected. One of the main functions of this function is to enhance the convenience of fingerprint locks. For example, when relatives at home need to stay for a few days, only when the fingerprints of relatives are entered in the fingerprint lock, relatives can freely open fingerprint locks, and do not need to configure relatives. It is very convenient. After the relatives have gone, they can't open the door as long as the information is deleted. When the nanny is at home, the nanny's fingerprint is deleted after the babysitter resigns. She can't open the lock. Don't worry about the nanny stealing the key and replacing the lock.

Fourth, anti-mite alarm function (non-essential, but very practical) Anti-mite alarm function can be said to be one of the most effective functions in the fingerprint lock function to enhance home security. When the fingerprint lock is damaged by external violence, it will automatically sound an alarm to remind the community security. Something better can even automatically send alert messages to the owner's mobile phone, or contact the police directly to make an automatic alarm, in order to prevent burglars from burglary.

Five, voice operation tips (non-essential, but very practical) voice operation prompt is that each link is a voice prompt operation, so that the operation is simple, so that people do not understand the operation can follow the prompts to complete the operation step by step, this feature It is very useful for the elderly and children.
