What kind of validation is needed?  Do you want to process the information as well or just check to see if the number and exp date are valid?  IF you want the latter, it is very simple to create a script to do that for you.. When you want to process the information and (make/check the charge) then it becomes a little more involved...

YOu would need to go through a "credit gateway" such as cybercash or another company that offers that ... I have no idea how to do it standalone.
