Introduction to the product

Description:

One of the implemented features for fleet management devices is 1-Wire data protocol, which can be used for iButton reading. It is the most straight-forward way to implement driver authorization in your vehicles.

1-Wire iButton 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.

Device configuration

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.
