Problems solved by technology

[0002] The existing fingerprint reader does not have the function of cleaning the finger pulp. Due to the moisture or stains on the finger pulp, it is difficult and time-consuming to identify the fingerprint. Secondly, when using the fingerprint to unlock related devices, the fingerprint is left on the fingerprint device and is easy to be copied by others. lead to poor security of the device

Abstract

The invention discloses a three-dimensional fingerprint identifier. The three-dimensional fingerprint identifier includes a wall body, wherein a fingerprint identifier main body is fixedly arranged inthe wall body; an identification window is arranged in the fingerprint identifier main body; a U-shaped fingerprint identification table is fixedly arranged in the identification window; an identification groove is formed in the fingerprint recognition table; and an information processing block is fixedly arranged on the left end face of the fingerprint identification table, and a scanning rotating groove is formed in the lower end wall of the fingerprint identification table in a communicating mode. Fingerprints are comprehensively scanned and identified through the scanning block, the identification efficiency is high, the fingerprints can be erased through erasure cotton, and the fingerprint identification device is high in safety and convenient to use.

Description

technical field [0001] The invention relates to the technical field of security devices, in particular to a three-dimensional fingerprint identifier. Background technique [0002] The existing fingerprint reader does not have the function of cleaning the finger pulp. Due to the moisture or stains on the finger pulp, it is difficult and time-consuming to identify the fingerprint. Secondly, when using the fingerprint to unlock related devices, the fingerprint is left on the fingerprint device and is easy to be copied by others. Resulting in poor security of the device. The present invention illustrates a device capable of solving the above-mentioned problems. Contents of the invention [0003] technical problem: [0004] Traditional fingerprint readers are easy to leave fingerprint information and be used illegally, and when identifying fingerprints, the contact between the finger and the reader needs to be clear, and the identification efficiency is low. [0005] In orde...
