org.apache.commons.validator
public class CreditCardValidator extends Object
Perform credit card validations.
By default, all supported card types are allowed. You can specify which
cards should pass validation by configuring the validation options. For
example,CreditCardValidator ccv = new CreditCardValidator(CreditCardValidator.AMEX + CreditCardValidator.VISA);
configures the validator to only pass American Express and Visa cards.
If a card type is not directly supported by this class, you can implement
the CreditCardType interface and pass an instance into the
addAllowedCardType
method.
