Abstract

Technique for ensuring that a device that contains coupons with barcodes will not output a barcode belonging to an invalid coupon to a barcode reading system. The technique avoids validation of the coupon at the time the barcode is provided to the barcode reading system. In the technique, the mobile device responds to a validity event that may affect the validity of a given coupon by inhibiting the provision of the given coupon'"'"'s barcode to the barcode reading system until the coupon has been validated on the basis of validity information available in the device that is outputting the barcode, and then again permitting the given coupon'"'"'s barcode to be output to the barcode reading system. In applications of the technique, the coupon may be used n times, the coupon may be shared, or the coupon may become valid after a set of actions have occurred.
