With Wiegand output, SF400 is flexible to connect with ZK or any 3rd party controllers as a slave reader. Wiegand input configures two SF400 units to utilize Master & Slave solution to enable users verification at both entrance and exit. Anti-passback function is also enabled to maximize the security level.
