Abstract
A smart card is disclosed which receives, decodes, and stores encoded data signals comprising redeemable coupons. Encoded data coupons are embedded within television segments and are transmit along with the normal television segments. The smart card receives the luminescent signals which comprise the encoded data coupons directly from the display. The smart card decodes the data coupons. The coupon is then stored within the smart card for future use. The smart card is equipped with an LCD which enables UPC codes corresponding to each of the stored coupons to be utilized. A scanner reads the UPC codes at the coupon redemption site. Once redeemed, the coupon is erased from the memory in the smart cad. Advantageously, all of the functions including receiving, decoding, and storing the data signals are performed by the smart card.
