There are two main methods:
PIN Entry: Employees use a personal identification number (PIN) to log their entries and exits in the system. This method typically involves using a keypad or touchscreen.
QR Code Entry: Employees record their clock-ins and clock-outs by scanning a QR code. Each employee has a unique QR code, which is usually scanned using applications on their smartphones.
These systems allow employers to easily manage employee work hours and accurately calculate labor hours. They also enhance workplace security by strengthening identity verification processes.
