At present, the accuracy of industry fingerprint identification mainly has two references, namely, the true rate and the false rate. According to the true rate, the fingerprint lock rejects the probability of actually recording the fingerprint. The false alarm rate is just the opposite of the true rate, which is the probability that the fingerprint lock accepts the non-recorded fingerprint. At present, there are no minimum or maximum standards for these two kinds of probabilities in the industry, and the probability between enterprises varies greatly. It is generally believed that a true rate and a false rate of less than 5% and five parts per million are acceptable ranges. The probability of this probability depends mainly on the resolution of the fingerprint recognition module. The current industry-recognized resolution standard is 500dpi, which is the minimum standard for ensuring clear, safe and reliable under the existing technical conditions. At present, the highest recognition rate of fingerprint locks comes from the industry giant Dijir, whose recognition rate is as high as 560dpi, and the fingerprint imaging is clearer and more accurate. Stability of electronic components Fingerprint lock is the perfect crystallization of computer information technology, electronic technology, mechanical technology and modern hardware technology. Electronic technology plays a decisive role in fingerprint locks, and its stability directly affects the security of fingerprint locks. If the electronic part is unstable, when you operate, the fingerprint lock may be unresponsive or perform other operations, and your instructions are innocent. For example, when you close the door, the electronic components are unstable and there is no lock command. Then the door is closed and not locked. It can be opened with a light push. This is a danger to the owner. The stability of the ferrule The ferrule is the force point of the whole lock, which is the most important part of the lock. The stability of the ferrule is the weight of the whole lock. If the ferrule is not stable, just use a few squats to complete the egg, even if the fingerprint lock The technology has reached the unattainable height is also a fantasy. The stability of the ferrule depends mainly on the material of the ferrule. At present, there are three kinds of materials for the most important ferrules in the industry, namely zinc alloy, iron and stainless steel. Zinc alloy has a lighter texture and is easier to mold. It is welcomed by manufacturers. The price is cheap and has a high strength, so it is often used as a ferrule material. Among the three materials, the most stable is stainless steel, which has a good effect in oxidation prevention and corrosion prevention, but the cost is high.
