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.
Designed for access control systems each key has a unique family code that is recorded while the key is being produced and the code cannot be overwritten
When you touch the ibutton reader with a tag, it reads this code and passes it to the tracker, which checks with the internal memory for its presence in the database. If the identifier with the code is found, the access rights are checked and give the actuators (locks, latches, latches or relays) the command to open/close.
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.
