1, fingerprint attendance. I believe everyone knows that the most traditional way of attendance is to identify employees' fingerprints by using biometric technology through fingerprint attendance machine. You can easily distinguish different identities of different people, so as to achieve the purpose of verifying identity attendance.

2, magnetic card attendance. Some traditional enterprises can use types of IC cards to enter and leave specific workplaces, including swiping cards to work, and calculate the attendance of employees through the transfer system. At the same time, the maintenance cost is low, which is generally purchased by enterprises.

3. Face recognition. In recent years, facial recognition attendance has been adopted by most enterprises. Through enterprises, employees' face images are first uploaded or captured by cameras in real time and entered into the system. After that, employees only need to stand in a specific position to shoot, and they can complete attendance.

4. Paper attendance. Enterprises use A4 paper, and employees sign in.
