Abstract
A system for toll payment by electronic cash identifies an electronic purse and effects value transfer over a communication system without stopping the mobile (vehicle or person). Mobile identity MID is temporarily correlated with purse identity PID and one or another identity is erased on satisfactory or non-satisfactory completion of the transaction thereby allowing non-payers to be pursued while preserving the principle of anonymity.
