How to identify the reject rate and error recognition rate of fingerprint lock? Fingerprint lock is a product that is accurately combined by electronic components and mechanical components. Its essence is safe, convenient and fashionable. For fingerprint locks, refusal rates and errors The recognition rate is undoubtedly one of the important indicators, then how do we identify the refusal rate and error identification of fingerprint locks?
1. The resolution of the fingerprints used, such as 500DPI. The precision of the existing optical fingerprint sensor is generally 30

For fingerprint locks, refusal rates and errors The recognition rate is undoubtedly one of the important indicators, then how do we identify the refusal rate and error identification of fingerprint locks?
1. The resolution of the fingerprints used, such as 500DPI. The precision of existing optical fingerprint sensors is generally 300,000 pixels, and some companies use 100,000 pixels;
2, percentage: For example, some parameters written.
Of course, these are all publicity parameters. Whether it is 500 dpi or the reject rate is less than 0.1%, this is only the concept of ordinary users, and cannot be detected;
3, in some extent, saying that truth and admitting false are complementary. This seems to be "hypothesis test" mathematical concept: at the same level, the rejection of truth is very high, and it is very low for false understanding, and vice versa.
This is a reactionary relationship. But why it is somewhat correct, because if the technical level is improved, both indicators can be lowered, so it should be substantially improved. In order to speed up authentication, some manufacturers reduce security levels at the expense of security to create fast and strong identification.
This is more common in this lock or demonstration lock. .
