Must understand the fingerprint lock terminology, it is worth collecting!

On the market today, all kinds of promotion is crazy, fingerprint lock stores is not exceptional also, launch a variety of benefit promotion, let a person dazzling. As the saying goes, 'the mutant ever victorious', and for the fingerprint lock of choose and buy friends, it is also necessary to understand the basic properties of the product when make, you know how much of fingerprint lock common terms? Know what is a 'resolution'? What is a 'recognize false rate'? Small make up today will give you a simple introduce some fingerprint lock industry professional term, let when buy. 1. What call boomed from 'truthful straightforwardness' ( FRR,错误拒绝率) , also known as the 'reject rate', a fingerprint recognition system is another key technical indicators, the source said the same fingerprint rejected matching probability. In other words, yao has been input fingerprint, but when you use the fingerprint system considered is not stored fingerprints, and the probability of dozen don't open the door. Like some people normally open a door with a fingerprint is fine, but occasionally there will be one or two dozen don't open the door after use according to the fingerprint lock. Boomed from the lower the fingerprint lock more stable, whereas the more unstable. In terms of the fingerprint lock industry, common boomed from around one percent, stability coefficient can also ascend. And solve the fingerprint really can't open the door from the effective way is by several more of the fingerprint. 2, what is the resolution of the resolution ( dpi） Is the understanding of the fingerprint reading head of fingerprint lock, as the principle of the pixels of the camera and the higher the pixels, shine the clearer; And the higher the resolution of the fingerprint reading head, the faster the reaction speed, to identify the more accurate, more stable performance. According to the fingerprint lock industry standard, fingerprint reading head, a resolution of 500 dpi resolution below this fingerprint reading head, reaction speed, the recognition accuracy and stability is not guaranteed. In general, the fingerprint lock in 500 dpi resolution, open time in 1 seconds. Below this value, open the door speed to 1 second or even a few seconds. 3, what is rate of course 'deterrent rate' ( 到目前为止,错误接受率) , also known as false rate, fingerprint identification system is a key technical index, it said should not matching the probability of the fingerprint was accepted by the system. Said is straightforward, with no input fingerprint fingers open probability of fingerprint lock. , for example, a person's fingerprint and no entry to the fingerprint lock, but when I opened the door with his fingers, fingerprint lock think his fingerprint information and have recorded a fingerprint matching, so automatic unlock. Deterrent to rate the level of relationship between the safety of fingerprint lock, deterrent to rate the lower the fingerprint lock more secure, conversely, the more insecure. In terms of the fingerprint lock industry, common deterrent rate at around one over one million, safety coefficient is relatively high. 4, what is called living recognition technology, according to the uniqueness and stability characteristics of biological living fingerprint, USES the real living fingerprint identification technology, can leather fingerprint recognition to the skin, and can be used to identify the subtle skin temperature, humidity, guarantee is only live for identification of advanced technology. Its important advantages is to avoid the duplicate fingerprints, dry fingerprint muddle through security technical problems. White-collar workers, for example, homemade fingerprint is used to clock in, in a biological living fingerprint identification technology of fingerprint lock can only be white blind here. Only human fingerprints can open it. ( Text content from locks the world)
