Credit card purchase of physical goods via an iPhone application

Question

I'd like to add a means for users do make payments for physical goods using credit cards via an iPhone application. Are there any guidelines regarding such functionality in iPhone apps? I'm mostly thinking of Apple's opinions on this.

Clearly, such data would have to be submitted securely but must this be done within Safari? If not, then how can a 'padlock level of trust' be established with the user? Would Apple even allow this?

Answer 1

There are some apps (see Tommy Hilfiger) that achieves this. However i couldnt find a clear answer on the issue either.

Answer 2

Amazon does it as well. Check out there app.
