Looks like you're in danger of re-inventing the wheel.  Interchange 
already supports numerous CC processing gateways.  Look at 
Vend::Payment.  You configure the gateway in catalog.cfg.

Interchange also comes with Vend::Payment::BusinessOnlinePayment, so you 
can make use of the many Business::OnlinePayment modules on the CPAN.

If you're targeting a gateway that's not supported by Vend::Payment or 
Business::OnlinePayment, the best approach would be to write a custom 
Vend::Payment subclass or a Business::OnlinePayment module for your gateway.

P.S. Can your client pass PCI/DSS if they don't upgrade to the latest 
version?
