I am not a developer, but I am just curious. I know you have the gift card, for example, and they scan it and it takes the money out. But what if they think its a fraud, an app that gets you free money. I don't want to go to Wal-Mart and pay for something with a gift card on Passbook and have them question its reliability. I want them to scan it, and go. Another question, when they scan it, will the red laser eventually distort the screen? Any help would be appreciated. I've been wondering these things for quite some time.
