An attendance machine is a device used to record and manage individual attendance. These devices often use advanced technologies such as biometrics, smart cards, or password recognition to accurately track and record the attendance of employees, students, or other groups. Deli attendance machines are mainly divided into face and fingerprint attendance. Face time clocks are suitable for scenarios that emphasize convenience and non-contact, while fingerprint time clocks are more suitable for environments that emphasize identity verification and high security. Deli's Face Attendance Machine and Fingerprint Attendance Machine provide organizations with a modern and intelligent solution to attendance management through the use of these biometric technologies.
