Vending machine with transponder interrogator

摘要

A vending machine includes a transponder interrogator. A customer carries a transponder embedded within an ornamental or useful item, such as a key chain ornament. When the customer desires to make a purchase from the vending machine, the customer presents the transponder to the transponder interrogator. The transponder is identified and a credit amount associated with that transponder is debited the purchase price. The system enables the vending machine operator to track the purchasing habits of the transponder user, and to provide instant incentives to purchasers using the transponder, based upon the customer's profile or purchasing habits.
