HF access control readers operate at 13.56 MHz and can support encrypted smart credentials, while low-frequency proximity readers typically operate at 125 kHz and use proximity credentials. Many HF readers also support low-frequency proximity, mobile credentials, and secure OSDP connectivity, which can help installers support existing credentials while transitioning to newer access methods.

Choose a single-gang HF access control reader for standard wallbox installations, a mullion reader for narrow door frames or other space-limited locations, and a keypad reader when users need PIN entry alongside card, fob, or mobile credentials. Also confirm the reader supports your credential migration plan, including 13.56 MHz smart credentials, existing 125 kHz proximity credentials, mobile credentials, and the required OSDP or Wiegand connection.

Yes, many HF access control readers support mobile credentials alongside high-frequency smart credentials, such as 13.56 MHz technologies. Depending on the model, they may also support 125 kHz proximity credentials, Bluetooth Low Energy mobile credentials, or keypad PIN entry, which can help support credential migration.

When selecting HF access control readers, compare high-frequency credential support at 13.56 MHz, low-frequency proximity support at 125 kHz, Bluetooth Low Energy or mobile credentials, and reader-to-controller connections such as OSDP or Wiegand. Also consider whether the system supports OSDP multi-drop wiring, which can connect multiple readers along one cable run and simplify installation.
