Simple and intuitive, without the need for computer knowledge, the price is relatively low. Disadvantages: cumbersome statistics, monthly replacement of cards, high mechanical failure rate (card sockets are easily damaged). Applicable scope: Units with less than 100 people and good environment. Magnetic card attendance machines can use computers to collect attendance data. Disadvantage: Magnetic cards and heads are vulnerable (perhaps there are more reliable magnetic card devices). Scope of application: Places with good hygiene environment and high personnel quality (mostly used for access control, banks, etc.).

Attendance machines have the advantages of improving management efficiency, avoiding human factors, diverse attendance methods, and data analysis and report generation, making them one of the important tools for modern enterprise management.
