When I first saw this, I had a different use-case in mind, where a person would just take a picture of their own credit card for an in-app purchase, instead of a vendor using it to accept money from another person. (Hence the focus on developers.)

If you AB tested giving someone a screen where they put in their credit card number, or a screen where they just took a picture of it, you might find that people are more willing to take a picture. People are probably more comfortable with a photo of their credit card being taken on their own phone than someone else's phone. To the app, both of these are CNP transactions.

That was my initial thought too. Instead of having to type all of your information using a tiny keyboard or on-screen one, you just snap a picture. I suppose, though, that most online markets allow you to save your information and the problem really isn't that big after the first entry. Something like this is kind of neat, but nothing new or novel. OCR has been good enough to do this for a long time.
