Yes.

Anything you need. A service is a class that isn't an entity, but provides an API to perform tasks.
In your case it will do SOAP calls.

isCardValid() doesn't belong to a repository. Though you could have a findValidCards() method in the
repository or a isValid() method in your model.

If you want to be pragmatic you can add isCardValid($no,$expDate,$cvc) perhaps as a static method to
the model or, as you suggested, to the repository. Conceptually it belongs to neither of them.

One of the idea of patterns is to have a common name for code structures. If everybody knows the
patterns its easier to discuss matters. But I agree that to get things started examples are most
welcome (the books about patterns usually supply them).
