Fingerprint lock can not be reliable, mainly to see three points

Introduction: Fingerprint locks have been gradually popularized in recent years, and technologies are maturing. However, most of the products on the market are domestically-made non-well-known brands. In the absence of a good certification body for identification, it is difficult for ordinary consumers to select What kind of fingerprint lock is safe to rest assured fingerprint lock? Let's take a brief look at the following.

1, the accuracy of fingerprint recognition

At present, there are two aspects of the accuracy of fingerprint recognition in the industry, namely, the accuracy and false rate. According to the truth rate, the fingerprint lock rejects the probability of a true fingerprint record. The false positive rate is just the opposite of the true rate, which is the probability that the fingerprint lock accepts non-recorded fingerprints. At present, there are no minimum or highest standards for these two probabilities in the industry, and the probabilities vary greatly between companies. It is generally believed that according to the truth rate and fraud rate of less than 5% and 5 parts per million are acceptable ranges.

The level of this probability is mainly determined by the resolution of the fingerprint identification module. Currently, the industry-recognized resolution standard is 500 dpi. This is the minimum standard that guarantees clear identification, safety, and reliability under the existing conditions. At present, the highest recognition rate of fingerprint locks comes from industry giant Dijer, whose recognition rate is as high as 560dpi, and fingerprint imaging is clearer and more accurate.

2, the stability of electronic components

Fingerprint lock is the perfect crystallization of computer information technology, electronic technology, mechanical technology and modern hardware technology. Electronic technology has a decisive role in fingerprint locks, and its stability directly affects the security of fingerprint locks. If the electronic part is not stable, the fingerprint lock may be unresponsive or perform other operations when you operate, and your instructions will not be ignored.

For example, when you close the door, the electronic components are not stable, and the door lock is not issued. At this time, the door is closed and unlocked. It can be opened by pushing hard. It is a danger to the owner.

3, the stability of the ferrule

The ferrule is the point of force of the entire lock, and it is the most important part of the lock. The stability of the ferrule is the most important thing of the whole lock. If the insert is not stable, it will be finished with a few steps, even if the fingerprint is locked. The technology has reached the height of nobody's enemy is also a fantasy.

The degree of stability of the ferrule depends mainly on the material of the ferrule. At present, there are three kinds of materials for the industry's most important ferrules: zinc alloy, iron, and stainless steel. Zinc alloys are lighter in texture and easier to mold and are welcomed by manufacturers. The price is low, and it has high strength, so it is often used as a core material. Among the three materials, stainless steel, which has the strongest degree of stability, has a good effect in terms of oxidation prevention and corrosion prevention, but the cost is high.

In fact, do not have to worry too much about the security of the fingerprint lock, as long as the election of the manufacturers, the selection of the brand, fingerprint lock is also very safe and convenient, it is not at ease can buy fingerprint lock at the same time, require the seller to produce the next chip and other components of the procurement documents Copy or directly open the fingerprint lock to see if the electronic components inside are fine and tidy.
