>Does anyone know of anything out there that just does credit card validation and not the whole shopping cart deal?

Basically each gateway provider has their own interface. I assume you're talking about the Web store - I've jsut wrapped several interfaces (PayFlow, AccessPoint and Linkpoint) which is all done via Fox code. It's not difficult and you'll have to do that on your own. Payflow from Verisign is an ActiveX control that takes about 10-15 lines of code to perform auth...
