1. Types, advantages and disadvantages of the attendance machine
1. Mechanical punching machine (combination of machinery and electronics)
Advantages: simple and intuitive, no computer knowledge is required, and the price is relatively low (available in office supply stores).
Disadvantages: cumbersome statistics, changing cards every month, the mechanical failure rate is high (the card slot is vulnerable to damage).
Scope of application: Units with less than 100 people and good environment.
2. Magnetic Card Time Attendance Machine Advantages: The computer can be used to count attendance data.
Disadvantages: The magnetic card and the magnetic head are vulnerable (maybe there is a more reliable magnetic card device).
Scope of application: places with better sanitary environment and higher personnel quality (mostly used in access control, banks, etc.).
3. The IC card attendance machine is roughly the same as the magnetic card, and the IC card socket is vulnerable.
4. The barcode attendance machine is used in the same way as the magnetic card.
Advantages: photoelectric reading barcode card number, low failure rate.
Disadvantages: Cards are easy to counterfeit (except for special stock-covered barcodes). After the barcode is dirty, the sensitivity decreases and there is a wrong code.
5. Proximity card attendance machine Advantages: non-contact card reading, no wear and error codes.
Disadvantages: The cost of cards is too high to solve the problem of "playing cards".
6. Fingerprint Time Attendance Machine Advantages: No need for cards, solve the problem of card punching.
Disadvantages: The quality of personnel is required, the fingerprints need to be clean, and the ability to prevent damage and stability needs to be improved (currently in the initial stage).
7. Eye Rainbow Time Attendance Machine Ideal time attendance machine.
Advantages: Use the characteristics of human eyes to identify different people, and use non-contact methods to identify the characteristics of people, the recognition speed is less than 1 second.
Disadvantages: At present, the cost is high and has not yet entered the Chinese market.
8. All attendance machines should have the necessary quality, accurate time, attendance data is not easy to be lost or confused by interference (occasionally unavoidable), and the communication with the computer is stable.
2. Attendance software
It seems that everyone can write time and attendance software. Whether it suits you depends on your requirements. Easy to use, stable and practical.
Third, the company's choice
Half of the success or failure of the time and attendance system depends on the company that provides you with the product. You can provide after-sales service within the period you require. Otherwise, your system will fail.
