There are some preliminary functions for accepting, validating and formatting credit card information included. These functions have not been tested (seriously, I haven't even checked to see if they do anything at all, yet). Therefore, please do *not* use them on any production sites without thoroughly testing them first. I would highly recommend never accepting credit card information directly, though, and would instead try to convince you to use a service like PayPal to accept payments, as there is no guarantee whatsoever that the information can be kept secure.
