title: Make App Store Promo Codes Scannable Like Starbucks Does?
body: <p>My app is in review and I'm trying to make some promo codes that are scannable so I can print them on cards similar to the "app pick of the week" by starbucks. They put the app promo code in a box and it is scannable using the app store app. I gave this a shot and it didn't work. Is this due to apple not allowing others to use this tech or is my image just the wrong size?</p>
