This device is in an automatic operating mode:

It automatically captures the UID or data from a Legic RFID data tag using customised firmware in the Legic module and outputs it as a keyboard input on the connected computer.

No drivers are required for this function; the device logs on to the computer as a standard keyboard.

If you also want to set postfixes and prefixes, you can use the HID Setting software to do this. Then save the settings with [SET] in the lower area of the software.

If you want to use special characters, you can use the USB Usage Tables to create your own command.
