A Biometric Feature Recognition Device for Reducing Interference of Overlapped Lines

Abstract

The invention discloses a biological identification feature identification device that reduces the interference of overlapping lines. In the groove, the display screen is installed on the top of the control buttons and is on the same plane as the panel. The rectangular groove on the right side of the back shell fits closely with the outer shell of the data output interface. The back shell is connected to the threaded columns around the panel through bolts. In summary, after the improvement of the present invention, regular cleaning of the interference factors on the surface of the pressing plate is carried out, and after cleaning, it is supplemented with anti-sweat and fingerprint spray, which avoids the surface wear of the pressing plate caused by long-term use, and at the same time improves the contact with fingerprints. The degree of fit further improves the recognition efficiency.

Description

technical field [0001] The invention relates to a biometric feature identification device, in particular to a biometric feature identification device that reduces the interference of overlapping lines. Background technique [0002] Optical fingerprint recognition is mainly based on the acceptance of light reflection and identification by comparing the detailed feature points of different fingerprints. It can well deal with some problems such as unclear lines caused by the twisting of lines during the pressing process of your fingers, but sometimes there are some problems. Recognition failure needs to repeatedly press the fingerprint to identify the problem: [0003] Some people cannot quickly identify a suitable object from the fingerprint library due to the shallow fingerprint path and the light feedback emitted by photoelectric fingerprints. They need to repeat the identification until they match before they can punch in successfully. And due to the dry skin in autumn and ...

[0003] Some people cannot quickly identify a suitable object from the fingerprint library due to the shallow fingerprint path and the light feedback emitted by photoelectric fingerprints. They need to repeat the identification until they match before they can punch in successfully. And due to the dry skin in autumn and winter, this The problem is particularly obvious
