Hand-held terminal, attendance checking equipment, electronic attendance checking system and attendance checking method

Abstract

The invention provides an electronic attendance checking system. The electronic attendance checking system comprises a hand-held terminal and attendance checking equipment, wherein the hand-held terminal is used for setting a scanning time period and an attendance checking manner, extracting corresponding user information to generate attendance checking request information within the scanning time period according to the set attendance checking manner, encrypting the attendance checking request information by using a produced random key and a preset encryption algorithm, scanning the attendance checking equipment matched with the attendance checking request information within the set scanning time period and sending the encrypted attendance checking request information; and the attendance checking equipment is used for receiving and decrypting the encrypted attendance checking request information, judging whether the hand-held terminal sending the attendance checking request information is an authorized user or not, generating valid attendance checking information if the hand-held terminal is the authorized user, generating invalid attendance checking information otherwise, storing the valid attendance checking information and feeding the valid or invalid attendance checking information back to the hand-held terminal. According to the electronic attendance checking system, the phenomenon that staff queue up in front of attendance checking machines for punching during rush hours is avoided, the phenomenon that the staff replace one another to punch in is completely eradicated, and meanwhile, the problem that the staff forget to punch in due to busyness or other reasons is solved easily.

Description

technical field [0001] The invention belongs to the technical field of electronic attendance management, and relates to an attendance system, in particular to a hand-held terminal, attendance equipment, an electronic attendance system and an attendance method. Background technique [0002] At present, enterprises and institutions use the attendance system to manage the attendance of employees. Therefore, attendance management is a very important link, and a strict attendance system is the premise and guarantee for doing a good job in various management tasks. With the development of electronic technology, there are many kinds of attendance systems that can realize electronic attendance, such as fingerprint time attendance devices and punch cards. Existing time attendance technology can be roughly divided into three types, [0003] The first is the traditional card time attendance, which requires the user to touch the card with the time attendance machine to complete a time ...

AI Technical Summary

Problems solved by technology

The disadvantage is that the efficiency of attendance is completely constrained by the performance of the attendance machine itself, and the changes to the existing attendance system are too large and the cost is high

[0006] Therefore, a new attendance system is needed for the current attendance technology in the peak period of commuting, queuing up in front of the attendance machine to punch cards, and the phenomenon of employees punching cards on behalf of each other.
