Overview
The ZKTeco F21 Lite is a fingerprint biometric attendance machine that doubles as a door access control terminal, suited to offices, factories and smaller commercial sites. Its BioID reader is built to cope with dry, wet and rough fingers, and anti-highlight and side-beam handling cuts the interference that can disturb a fingerprint read. Infrared sensing activates the device when a finger is presented, which keeps power use down between users.
- 2.4-inch TFT colour screen for enrolment and on-device status
- 3,000 fingerprint templates, 100,000 transaction records, and an optional 5,000 card capacity (ID or 13.56 MHz S50/S70 IC)
- ZKFinger VX10.0 algorithm running on the ZMM220 platform at a 1.2 GHz clock rate for quick verification
- Access control interface for a third party electric lock, door sensor, exit button, alarm and doorbell
- Wiegand signal input and output, plus SRB (secure reader board) support
- One auxiliary input to link a wired detector or an emergency switch
- Anti-passback, scheduled bell, automatic status switch and DST (daylight saving time), with optional printer support
- RS232/485, TCP/IP and USB-host communication
Works with ZKAccess 3.5 software, and a standalone SDK is available for custom integration.
Budget for a 12 V DC 3 A supply and the door hardware (electric lock, exit button, door sensor). An RFID reader, alarm sensor and an RS232/485 converter are listed as optional accessories. Tell us the door count, the card type in use and whether you need attendance reporting, and we will quote the full set.
