Abstract: Implementations include actions of receiving an image of a vehicle using a toll road facility, processing the image to determine a vehicle identifier, and determining that the vehicle identifier is provided in a database, the database associating vehicle identifiers to respective device identifiers, and in response: determining a device identifier associated with the vehicle identifier from the database, transmitting a first message to a device associated with the device identifier, the first message including a request for approval to collect a toll payment, and receiving a second message from the device, the second message indicating approval of the toll payment, and in response: transmitting a payment request to a service provider, the service provider providing data transfer services for the device, and receiving the toll payment from the service provider.

Abstract: Implementations include actions of receiving a first tag identifier based on a first vehicle using the toll road facility, and determining that the first tag identifier is provided in a registration database as indicating a no-contract tag, the registration database associating no-contract tags to respective device identifiers, and in response: determining a first device identifier associated with the first tag identifier from the first database, transmitting a first message to a first device associated with the first device identifier, the first message comprising a request for approval to collect a first toll fee, and receiving a second message from the first device, the second message indicating approval of the first toll fee, and in response initiating payment of the first toll fee from one of a prepaid account associated with the first tag identifier or a first service provider, the first service provider providing data transfer services for the first device.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for receiving a first message, the first message including information associated with an invoice. Obtaining an invoice number assigned to the invoice based on the information. Obtaining a vehicle identifier based on the invoice number. Registering a device for electronic payment of toll fees at least partially based on the vehicle identifier. Transmitting a request for payment of at least a toll fee that is identified in the invoice.

Abstract: Implementations are directed to collecting toll fee for use of a toll road facility. In some implementations, actions include receiving a first signal, the first signal indicating that a first device is in a vehicle using the toll road facility, processing the first signal to determine a first device identifier, and transmitting a first message to the first device, the first message comprising a request for collecting a first toll payment.
