There are services like Maxmind that do fraud screening, which could be done before submitting a transaction to a payment gateway.
Basically the service returns a fraud potential score, and you can dictate if it is low enough to perform a transaction. There isn't anything baked-into CF to do this. There may be some CF libraries that do a number check to see if the cc number itself is valid, as this is a common algorithm, but more advanced filtering would be through another service.
