[Zope] Newbie:Credit-card question

[brocken22@gmx.de]

Hallo,
that's my problem:
I'd like to build up a shopping-system that's working with
credit-cards(it's the customers wish).
It's the first time I have to deal with this.
How is the checking of the valid credit-card-number being done??
Which institution must be contacted by the server?? In realtime ( I mean
is the contact with the client browser being held)??
Is this possible with Zope and in which way??
           Thanks for the help
                              Sven
