What is a Transponder?
Transponder is an electronic communication device that interacts with the toll collection devices and issues an automatic charge. No need to spend time looking for coins, bills, or making a hands-on transaction which eases up vehicles.
How Transponders Work:
- The transponder is placed on the windshield and activated a signal for toll booths.
- It denotes the identification of the vehicle, then tolls are automatically taken off a pre funded account.
- Some transponders also provide integration with a parking lot feature.
Considering these facts one can see that transponder and vehicles interaction is more complicated than expected.

Scenarios Where Sharing is Allowed:
