F22 is an ultra-thin fingerprint time attendance and access control terminal from ZKTeco, built with Wi-Fi connectivity and an advanced algorithm for reliability, precision, and excellent matching speed. It features the fastest commercial-based fingerprint matching algorithm alongside ZKTeco’s high-performance, high-image quality infrared detection fingerprint sensor.

The F22 provides a superior touching experience through its touch keypad, offering genuine flexibility for either standalone installation or integration with any third-party access control panel that supports standard Wiegand signal. This makes the F22 well suited for organizations that already have an access control panel in place and simply need a reliable fingerprint reader to add to it.

The F22 supports 3,000 fingerprints (optional) and up to 5,000 ID or Mifare cards (optional), with a transaction capacity of 30,000. Its Z-ID Sensor, paired with the ZKFinger V10.0 algorithm, delivers reliable fingerprint matching across a 2.4-inch TFT LCD color screen that keeps the interface clear and responsive.

Communication on the F22 is genuinely comprehensive: RS232, RS485, TCP/IP, USB-Host, and Wi-Fi are all supported, giving installers flexibility across different network environments and legacy wiring setups. Wiegand signal support covers both input and output, letting the F22 either send its own verification data to an external panel or receive it from another reader — a real advantage for integrating into an existing access control ecosystem.

The device includes a dedicated interface for 3rd party electric lock, door sensor, exit button, and alarm connection, letting it function as a standalone access control device when a separate panel isn’t needed. An auxiliary input is also included for linkage functions, extending the F22’s ability to trigger or respond to connected equipment.

Standard functions include DST (Daylight Saving Time), Automatic Status Switch (optional), Record Query, T9 Input, 14-digit User ID (optional), Anti-passback, Scheduled Bell, optional printer support, and ADMS for centralized device management. Anti-passback is a particularly useful inclusion, helping prevent a single credential from being used to let multiple people through the same access point.

Compact at 158.5 x 78.0 x 19.4mm, the F22 runs on a 12V DC, 3A power supply and operates across a 0°C to 45°C temperature range with 20%-80% humidity tolerance. It’s supported by a Standalone SDK and ZKBio Access IVS software. For organizations that need a genuinely fast, flexible fingerprint terminal capable of standing alone or integrating with existing access control infrastructure, the F22 offers a well-rounded, thin-profile solution.
