Fast, reliable performance combined with affordability gives ZK readers the competitive edge. Each reader has the capacity to store up to 2,200 fingerprint templates and 30,000 transactions. Enrolling users is fast and easy since most of our readers have a user-friendly keypad and display. Managing our readers is also simple. All our readers are easily accessed through a TCP/IP or serial port, with the ability to automatically update and synchronize when networked together.
