Speedup for monetary transactions using a transponder in conjunction with a smartcard

摘要

This invention allows a user to have a smartcard (66) and a smartcard-based transponder (14). This smartcard-based transponder (14) can accept money from the smartcard (14). The amount transferred from the smartcard (66) can be stored in the transponder memory (80,82). At a toll plaza (29), a toll amount can be subtracted within a short period of time, so that a vehicle (26) bearing the transponder (14) will not pass through the zone in which the transponder (14) and the interrogator (12) may perform RF communications before an appropriate toll amount can be decremented from the amount stored within the transponder (14).
