With an estimated 25-35% of the U.S. population with smart phones, QR usage is really beginning to take off. There are many applications for these on Fusion Digital Paper ??products. One that comes to mind is in use with our Fusion Digital Peel N Stick Postcards. The recipient could stick the postcard within easy view (in a kitchen for example) and then scan the QR code printed on the postcard from time to time for timely product offers.
