Abstract: A method and system for making payment of a transacted price to which a discount is applied using a mobile terminal for receiving geographical location information for establishing a discount to be applied to a purchase from at least one discount medium available within the area of the location of the mobile terminal with the user of the mobile terminal selecting a discount from the available discount medium and with the method and system using temporary card numbers generated from a temporary card number issue device for paying the transacted price less discount. An issued temporary card number includes the discount selected by the user and includes temporary card number issue information which is transmitted to the mobile terminal.

Abstract: Disclosed is a method and system for making payment with discounted prices using temporary card numbers and temporary card number issue information including at least the discount location selected by a user, discount medium and payment medium. The user's mobile terminal transmits the temporary card number issue information to a temporary card number issue device for generating a temporary card number with the temporary card number information and transmitting the selected temporary card number to the mobile terminal for transmitting the generated temporary card number and temporary card number issue information to a credit authorization terminal (CAT) to request transaction authorization to approve payment of the transacted price less a calculated discount based on the temporary card issue information subject to the proviso that the payment authorization is requested within a predetermined time following the issuance of the temporary card as the temporary card is voided.

Abstract: Disclosed is a method and system for making payment with discounted prices by using temporary card numbers.

Abstract: A system and method for managing electronic receipts of sales transactions utilizes a receipt capture device that generates receipt data using information from a point-of-sales (POS) terminal and a mobile device that receives the receipt data from the receipt capture device using short range communication.
