Abstract
An RF roadway toll collection system uses an upstream reader to communicate with a vehicle borne transponder carrying a Smart Card to calculate the toll and debit the Smart Card balance in the amount of the toll payment required. A transaction manager is notified of the toll payment from the upstream reader and notifies a downstream reader of the vehicle identification and payment status. The downstream reader confirms the vehicle identification and payment status and signals if the toll has been paid.
