An attendance machine is an electronic device used to record employee attendance. It can automatically record the commuting time, tardiness, early departure, and leave of employees, helping companies better manage their attendance. At the same time, attendance machines can also be combined with enterprise management systems to provide more comprehensive employee management functions.

The barcode attendance machine uses photoelectric reading of barcode card numbers, resulting in a low failure rate. Disadvantages: Cards are prone to forgery (except for specialized stock masking barcodes), and the sensitivity decreases and there are errors when the barcodes become dirty.
