Scanning a QR code with the order details means that I can verify an order is real and not a forgery, and also show me the most pertinent details for the purpose of an onsite event. In our case that would be celebrity photo ops (as well as additional purchase upgrades such as digital copies or extra prints). It makes sense for everyone on this thread. That's why we're asking for it. It doesn't have to make sense to you to be a valid request.
