First of all, employees must be enrolled in the time clock system to register their punch in and out times. When enrolled, the software records the employee’s fingerprint template and then associates it with their ID number.
The fingerprint templates are different for each employee. This allows the system to distinguish between them.
Every time an employee punches in or out, the software verifies the scanned fingerprint with the stored templates. If a match is found, the clock times are recorded.
