Set of RFID card and 1-wire RFID reader

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 convenient 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 in these use cases:

• Immobilizer – prevent anyone from starting the vehicle without scanning an RFID tag first.
• Authorized driving – keep track of who is driving your vehicle according to the RFID tag they use to authenticate themselves.
• Auto Geofencing – gives ability to know when car leaves customized areas without RFID authorization.
