A vehicle charge meter for tracking a path of a vehicle is described. The vehicle charge meter comprises a receiver, a memory, a local controller, and a receipt documentation device. The receiver, the memory, and the receipt documentation device are all coupled to the local controller. The receiver is used for receiving RF signals and extracting positioning data from the signals. The memory includes a database storing relationships between positioning data and toponyms. The local controller is then used for retrieving at least one toponym corresponding to the extracted positioning data. As such, the receipt documentation device can document the retrieved toponym in an electronic receipt or on a paper receipt.
