Work attendance system and method

The invention relates to a work attendance system and method. The work attendance system comprises a controller, a Bluetooth module and at least one mobile terminal with a built-in Bluetooth transmission unit. The mobile terminal sends check-in information to the Bluetooth module in a Bluetooth mode via the Bluetooth transmission unit. The Bluetooth module is used for receiving the check-in information and transmits the check-in information to the controller. The controller is used for receiving the check-in information, comparing the check-in information with employee information stored in an internal storage module so as to determine a check-in employee, calling an internal clock chip, determining the check-in time of the check-in employee according to time when the controller receives the check-in information, and generating a work attendance table on the basis of analysis of employee information, all the check-in employees and check-in time. The work attendance system employs a Bluetooth transmission manner, so cost of the integral system is reduced, and intelligence and operationality of the system are improved.
