The F21 is a fingerprint terminal for door access and staff attendance, using ZKTeco's SilkID sensor. SilkID reads dry, wet, and rough fingers reliably, which reduces failed scans on building sites, in kitchens, and in workshops, and it detects live fingers to reject fake prints.
It stores 3,000 fingerprints, 5,000 ID or IC cards (optional), and 100,000 transactions. A camera records a photo at each attendance event, with photo ID available as an option.
It connects to an electric lock, door sensor, exit button, alarm, and doorbell, supports anti-passback, and has Wiegand input and output. An auxiliary input can link to a fire detector or emergency switch to release the door. It communicates over TCP/IP, RS-485, RS-232, and USB, and supports a scheduled bell.
It runs on 12 V DC. We install it, wire the door, and connect it to ZKBio Access or your attendance software.
