It seems to me that all this app does is OCR your name/number/date, instead of having you type it in. I'm sure there will be some users who will be wary of it, but it's not like it can get any more info than you would type into a game or whatnot.
Of course, I'm not sure how this is useful, since I understand that in-app purchases need to be tied to the App Store account, but it might be more useful for Android.
