Feel the charm of biometric fingerprint, the characteristics of fingerprint attendance machineby CCTV store Home Security Camera Supplier
Fingerprint attendance has many characteristics, for instance, recognition speed is quick, accurate, convenient, let the intelligence of check on work attendance. But in the use is limited by the fingerprint of the membrane life, high-end machine fingerprint attendance machine do improve the breakthrough in this field.
Fingerprint identification system is through the special photoelectric conversion device and computer image processing technology, the living fingerprint collection, analysis and comparison, can quickly and accurately identify the personal identity. System generally includes fingerprint image collection, fingerprint image processing, feature extraction, feature value than and matching process. Modern electronic integrated manufacturing technology makes the fingerprint image read and process equipment miniaturization, the rapid development of the personal computer operation speed provides a fingerprint on the microcomputer and single chip microcomputer can compare the possibility of operation, excellent fingerprint processing and matching algorithm ensures the accuracy of identification results.
Therefore, the fingerprint attendance machine in the finger skin in good Angle in the right direction when close to the fingers, gently press the work attendance can be completed.
The key part of the fingerprint attendance machine, also called the most vulnerable parts is fingerprint membrane. Fingerprint membrane, the longer the time with the fingerprint recognition rate is low, in the absence of any man-made scratch damage, a fingerprint membrane in a year later can more and more does not recognize a fingerprint or requires repeated recognition, the solution is to replace the fingerprint of membrane, change a fingerprint membrane need hundreds of Yuan, excluding the service charge, is a separate charge the cost of raw materials, usually to be replaced in a year or so.
