Biometric recognition feature recognition device capable of reducing interferences of overlapping lines

Abstract

The invention discloses a biometric recognition feature recognition device capable of reducing interferences of overlapping lines. The structure of the device comprises a recognition module, a rear shell, a data output interface, a panel, a display screen and a control key; the recognition module is nested in a groove at the right side of the front end of the panel; the display panel is installedat the top of the control key, and is in the same plane as the panel; a rectangular groove at the right side of the rear shell is tightly attached to an external shell of the data output interface; and the rear shell is fixed with threaded columns around the panel through bolts. In conclusion, after the improvement of the biometric recognition feature recognition device, surface interference factors of a pressing plate are regularly cleaned, and the anti-sweat liquid and the fingerprint spray are supplemented after cleaning, so that the surface abrasion of the pressing plate caused by long-term use is avoided, meanwhile, the fit with fingerprint contact is improved, and the recognition efficiency is further improved.

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
