    EN)A computer-implemented system for verifying vehicle usage comprising a server capable of communication with a plurality of clients across a communications network. Each client is provided in a respective vehicle and with a respective global positioning system (GPS) by which the client can determine the location of the respective vehicle. A first of the clients sends a token to a second of the clients when the respective vehicles are within a valid range of one another. One or both of the first and second clients modifies the token to include information dependent on the location of one or both of the vehicles when the token is exchanged. The modified token is returned to the server which extracts the location dependent information from the modified token. This allows validation of the returned token. Validated tokens can be used in the assessment of vehicle usage and toll calculation. The system can offer a high level of privacy to users as well as being robust against fraudulent use.
