MyLaps Rental Karting Transponder

Rental Kart Transponder - MyLaps 

The Rental Kart Transponder is installed permanently on the kart and doesn't require any maintenance. The transponder sends a unique signal to the detection loop, which is used to identify the driver and record the exact time at which the kart passes by.

Note: This transponder is used by rental kart facilities, not racing organizations.
