Tomahawk validateCreditCard tag

This tag is used to validate a Credit Card Number entered by the user. If we want the user to enter a valid Credit Card Number then this validation can be done by this tag. If we don't want to allow any of the "American Express","Visa""mastercard" or "Discover" then we can set value false for the attributes "ameex","visa""mastercard" and "discover". If we don't want to allow anyone then we can set value true for the attribute "none". If the entered value is not a valid then we can display the message of our interest by using "message" attribute.
