CONNECTED TOLL PASS

Examples are disclosed that facilitate provisioning of a toll system communication device used in an electronic toll collection system, such as EZ Pass. The toll system communication device (e.g., an EZ Pass tag) can have user credentials provided to it that are associated with a user payment account. As a user travels a toll road, the toll system communication device is interrogated at a toll booth location. In response to the interrogation, the toll system communication device provides information identifying the toll system communication device and associated user credentials. The user credentials may be obtained from or authenticated with a mobile device within close proximity to the vehicle equipped with the toll system communication device. Using the user credentials and the identifying information, a user payment account may be provisioned to pay tolls accrued by the vehicle using the toll road.
