Constellation Wines and Cellar Key are featuring 2-D bar codes for mobile scanning on cards that hang on wine bottles.
Two-dimensional bar codes are beginning to sprout up in retail, sometimes in the most unexpected of places.
Take, for example, on the card that hangs off the neck of a bottle of wine. Constellation Wines this holiday season has included 2-D bar codes on their promotional wine bottle cards, as well as in newspaper inserts, to provide customers with a bounty of information and, hopefully, boost wine sales.
