One of the implemented features for fleet management devices is 1-Wire data protocol which can be used to read RFID tags by emulating them using iButton protocols. It is a practical way to implement driver authorization in your vehicles if you want to use RFID tags with minimal setup complexity.
1-wire RFID readers are great for these use cases:
Immobilizer - prevent someone from starting the vehicle without first scanning an RFID tag.
Authorized Driving - keep track of who is driving your vehicle according to the RFID tag they use to authenticate themselves.
Auto Geofencing – allows you to know when the car leaves customized areas without RFID authorization.
