An electronic coupon or voucher display includes a dynamic time-limited visual indicator that permits personnel at a vendor or merchant to confirm the validity of the coupon or voucher based solely on visual inspection of the dynamic time-limited visual indicator, without the need for scanning of the coupon or voucher, input of a coupon or voucher code, or communication with the coupon or voucher issuer. Display of the dynamic time-limited visual indicator is store or location specific and initiated following selection of a store or location, notification that a coupon or voucher is available and indication by the user of an intention to redeem the coupon or voucher, and a determination that the coupon or voucher is accepted at a detected location of the portable electronic device on which the coupon or voucher is to be displayed. |
