Abstract
In an electronic toll collection system, card data of a payment card is stored in an on-board unit mounted in a vehicle. Toll data necessary for a toll collection transaction including the card data is copied from the on-board unit to a cellular phone. A user passes the cellular phone to a tollgate attendant, and the toll data is moved to a toll collection unit installed at a tollgate. The toll collection unit calculates a toll fee based on the toll data and generates a delete command and road use data. When the tollgate attendant passes a portable terminal of the toll collection unit to the user, the delete command and the road use data are copied to the on-board unit. The toll data is deleted from the on-board unit by the delete command, and the road use data is reported to the user.
