Perfect Accessory for any application where AVL data needs to travel along with a person or object identification.   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 the ability to know when a car leaves customized areas without iButton authorization
