[ic] Credit card handling

[Interchange server]

Hello group,

I've put together a few pages about setting up credit card handling.
Most people in this group will run into these topics sooner or later,
and I'm sure quite a few people here are more knowledgeable about the
subject than I am at this point. If I have missed something or if I'm
uttering complete nonsense in the document mentioned below, I'd be glad
to receive comments about it.
