POINT-OF-SALE SYSTEM IMPLEMENTING CRITERIA-BASED TRANSACTION TOTALS

摘要

The Present Invention comprises the steps of determining a first transaction total price and a second transaction total price, for which the consumer is eligible upon the satisfaction of certain criteria. The first total transaction price is sent from a cashier terminal to a payment interface. Further information, such as an indication of the method of payment presented to the payment interface, is sent from the payment interface to the cashier terminal. The Present Invention then determines whether the consumer is eligible for the second total transaction price by using the further information to determine if the required criteria is satisfied. If the criteria is satisfied, the cashier terminal then sends the second total price to the payment interface.
