High-efficiency fingerprint identifier

Abstract

The invention relates to a high-efficiency fingerprint identifier comprising a pedestal. A drive ring is installed on the pedestal; and an elastic touch cylinder is arranged inside the drive ring coaxially in a sleeving manner. The drive ring can rotate freely around the axis of the drive ring relative to the elastic touch cylinder. Besides, an identifier unit and a positioning device are fixedly installed on the inner annular surface of the drive ring between the drive ring and the elastic touch cylinder; and the connecting lines of the centers of the identifier unit and the positioning device is intersected with the axis of the drive ring. The identifier unit is in an arc shape; and an identification surface of the identifier faces the elastic touch cylinder directly. The positioning device includes an infrared detection head facing the elastic touch cylinder. The drive ring is driven by a drive motor to make rotation. The drive motor, the identifier unit, and the positioning device are connected with a computer chip respectively. The fingerprint identifier having the exquisite structure is capable of aligning at a fingerprint dynamically and efficiently, thereby improving the fingerprint obtaining success rate.

Description

technical field [0001] The invention relates to an electronic identifier, especially a fingerprint identifier. Background technique [0002] With the advancement of science and technology, people are developing more and more accurate encryption systems. At present, relatively high-end encryption systems include iris scanning, bioelectric scanning, fingerprint scanning, etc. Currently, fingerprint scanning is more commonly used by the public and at a lower cost. , so fingerprint scanning is gradually promoted in all walks of life, and even the national security department will use fingerprint recognition to manage personal information; for example, when applying for personal documents at the police station, fingerprints need to be taken; when taking fingerprints, the applicant's fingers need to be close The touchpad is kept on for 5-10 seconds.

[0002] With the advancement of science and technology, people are developing more and more accurate encryption systems. At present, relatively high-end encryption systems include iris scanning, bioelectric scanning, fingerprint scanning, etc. Currently, fingerprint scanning is more commonly used by the public and at a lower cost. , so fingerprint scanning is gradually promoted in all walks of life, and even the national security department will use fingerprint recognition to manage personal information; for example, when applying for personal documents at the police station, fingerprints need to be taken; when taking fingerprints, the applicant's fingers need to be close The touchpad is kept on for 5-10 seconds. The touchpad of the traditional fingerprint reader is horizontal and flat. When placing the finger, the user needs to keep twisting the wrist and pressing the touchpad. During this process, the hand is more sore and the hand shakes It will affect the admission of fingerprints; therefore, in the fingerprint enrollment process, the one-time success rate of fingerprint enrollment in this way is not high; especially when enrolling children's fingerprints, children are naturally active, which greatly affects the work progress and delays other waiters If the waiters and staff are disturbed many times when taking fingerprints, they will feel irritable. This irritability will infect the entire studio, which will make the staff's attitude bad and affect the service attitude. One of the reasons for the bad attitude of the department
