Description:
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 iButton first.
- Authorized driving - keep track of who is driving your vehicle according to the iButton ID they use to authenticate themselves.
- AutoGeofencing – gives ability to know when car leaves customized areas without iButton authorization.

Installation
To connect the 1-wire RFID reader, simply connect the 1-Wire Signal wire from the reader to the 1-Wire Data pin on the device, connect the 1-Wire Power wire to the 1-Wire Power pin and connect the ground wire to the same grounding used for the device.

| 3 | GND (-) | Ground |
Device configuration
Since this reader emulates received RFID values as iButton values, it has identical functionality as the iButton reader in this regard. The reader works as soon as it is connected, but the iButton isn't used anywhere other than displayed in the iButton I/O element. In order to use it for the Immobilizer scenario, the device must have the scenario enabled. Then, iButton check can be enabled to only accept iButtons specified in the iButton list under the 1-Wire tab.
