Keyboard: For the Keyboard when Creating a New Racer you must assign a unique key to each racer, for example 1 or j. Any key can be used except for r,s,e and p which are reserved for Keyboard Shortcuts.

Core Speedway: For the Core Speedway hardware the UID is based on the UID of the RFID in the car. When Creating a New Racer the scan button will pick up the RFID's UID.

Kyosho IC: With the Kyosho IC lap counter the UID of the RFID is not used. Instead each RFID must have a unique block of data on block 1 of the memory on the RFID. Kyosho tags and dNaNo's already have a unique block of data but generic tags will not. Generic RFID tags will have to be initialized to work with the Kyosho IC lap counter. Refer to the Using Generic Tags with the Kyosho IC Lap Counter section of the Advanced Topics chapter for further information.

I-Lap: The I-Lap transponders provide a 7 character transponder id that the software detects and will use as the UID.

Robitronic: The Robitronic transponders use a 2 byte transponder id that the software detects and uses as the UID. With only 2 bytes used it is possible there will be duplicate id's as there can only be a maximum of 65536 id's created. So will possible it is fairly unlikely you will encounter a duplicate transponder id.
