Stop time theft at the door
Manual sign-in sheets and unverified mobile check-ins can be gamed — a colleague clocking in for another is a common source of payroll leakage. ZKTeco's biometric terminals verify identity at the physical checkpoint, so what's recorded in OnTap is what actually happened.
- Fingerprint, facial recognition, and RFID card verification at the terminal
- Attendance events sync automatically into OnTap — no spreadsheets, no manual capture
- Works across multiple ZKTeco terminal models via standard SDK/API connectivity
- Device continues logging offline and syncs the moment connectivity is restored
- Feeds directly into OnTap payroll, overtime, and shift-scheduling calculations
