are you talkin about validating it to check whether it is REAL or whether the format is correct ?

You can check if they have entered a valid number and that is about it. It would be irresponsible to expect customers to provide credit card information through an unsecured form.

For complete validation, check with your hosting company if they can recommend a secure service or if they can provide a secure connection. In fact, if I don't see a form is secure, I won't order the item.
