ZKTeco F21 Access Control + Time Attendance Solution. Fingerprint, Cards and PIN

The ZKTeco F21 Access Control and Time Attendance Terminal is a smart solution for managing who enters and leaves your building. Whether it’s for a business, school, or office, this device uses fingerprint, card, and PIN options to verify identity. It stores up to 3,000 fingerprints and can also recognize up to 5,000 ID or IC cards, giving you flexible and secure ways to manage access. With a colorful 2.4-inch screen, users can easily follow instructions or view their status on the device. This device is more than just an access control terminal—it’s also a time attendance solution. It can save up to 100,000 transaction records, which means it keeps track of clock-in and clock-out times for many employees without needing to constantly clear its memory. It’s built to connect with other door security components like electric locks, sensors, exit buttons, alarms, and even a doorbell. This makes it perfect for locations that need to control who can come in and out.

Communication is made easy with support for RS232, RS485, TCP/IP, and USB-host. This means you can connect it to your network or computer in different ways, depending on your setup. If your location uses Daylight Saving Time (DST), the device can automatically adjust the time. It also comes with automatic status switching, so it can change modes based on a schedule you set, like switching from entry mode to attendance mode at certain times. Extra features include anti-passback, which prevents someone from using a card or fingerprint to let in another person who isn’t authorized. It also has a scheduled bell, which is useful for schools or workplaces that want automatic alerts at certain times. If needed, you can also connect an optional printer to print attendance logs or reports directly from the device.
