Abstract
This invention allows a toll authority to monitor transaction numbers which are sent from a transponder (,) to an interrogator (,). By incrementing the transaction counter stored in the transponder with successful transactions the toll authority can ascertain whether accounting of a transaction has been missed (i.e., a transaction number missing from the sequence), or double-counted (i.e., two transactions with the same transaction number).
