SF 100
ZKTeco SF100 Device – IP Based Fingerprint Access Control & Time Attendance Terminal.

The ZKTeco SF100 Device is an IP-based fingerprint terminal that can work in both network and standalone modes. In network mode, it can connect to ZKAccess3.5 software for access control and time attendance management. The device has a Wiegand output that makes it flexible to connect with ZKTeco or any 3rd party controllers as a slave reader. Additionally, the Wiegand input allows two units of SF100 to be configured with each other and utilize a Master & Slave solution, which requires user verification at both entrance and exit. The SF100 also has an anti-passback function to maximize security. It has an auxiliary input interface that allows it to connect with an external source, such as a smoke detector or emergency switch. Once the linkage function is enabled through the machine menu, the device generates an alarm signal and opens the door in case of an emergency.
