Also known as radio frequency identification technology, also known as radio frequency identification, is a communication technology that can identify specific targets and read and write related data through radio signals without the need to establish mechanical or optical contact between the identification system and the specific targets.
Face recognition attendance
Use a camera or camera to collect images or video streams containing faces, and automatically detect and track faces in the images, and then perform a series of related technologies on the faces of the detected faces to achieve the purpose of identifying different people machine.
That is, the built-in printing device can directly print out the time attendance record of the original attendance record, and the punch type is divided into an electronic type and a mechanical type.
Fingerprint recognition time attendance
It refers to the time and attendance machine for identification by comparing the detailed feature points of different fingerprints.
That is, the built-in printing device can directly print out the attendance record of the original attendance record.
The probability that the fingerprint time attendance machine does not recognize the registered fingerprint, the lower this parameter is, the better, it means that the possibility that the authorized fingerprint is not recognized is smaller.
False acceptance rate
Fingerprint time attendance incorrectly considers the probability of an unregistered fingerprint as a registered fingerprint, that is to say, it is clear that it is not registered, and it is indeed possible to attendance.
