RFID reader.jpg

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 RFID card first.

Device configuration

TFT100 iButton Read Notification.png

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.
