Answer 1

You need to do very serious research into this and not necessarily accept what people on this site say without thorough research and confirmation on your part.

Storing information like credit card info is not something you should implement just based on responses on this site IMO.

If you are serious you need to read, understand and apply the material in the book "Hacking And Securing iOS Applications" to understand what the dangers are and how you can mitigate against them, and how techniques that people say are secure really aren't as secure as you think they might be.
