If I had a store, I think I would deliberately put scanning information into place as a service. Love this line? Scan the QR code to link to an online pattern and tutorial. Scan here to see customer quilts made with similar lines. Enter your quilt or work in progress in our photo gallery for a chance to win a free prize.
I like this idea, it's brilliant, and would be yet another draw for the store, especially if I could track my purchases from that store easily in an app. "What did I buy last time? Let me see!" Maybe have a set up where you could scan a code and "subscribe" to a fabric, get a notification if it goes on sale...
So many opportunities there.
