ZKTeco BioPro SA20 Biometric Attendance Machine
A compact fingerprint attendance terminal with a color touch screen and built-in access-control outputs for doors and alarms.
A fingerprint-based time and attendance terminal built around a 2.4-inch TFT color screen for fast, clear interaction at the door.
Its Bio ID fingerprint reader adds anti-interference technology and a sensor-activation function, so the scanner only wakes and reads when a finger is actually present, cutting down on false triggers.
Card-based verification is available as an optional add-on alongside fingerprint, giving flexibility in how staff check in.
Access-control features go beyond simple logging: anti-passback, and direct wiring for an electric lock, door sensor, exit button, alarm, and doorbell make it a full door-entry controller, not just a clock.
A built-in auxiliary input lets it link to an external wired detector or emergency switch, useful where the terminal also needs to react to a physical security event.
