CardValidator Component [E-Payment Integrator V5]

Properties Methods Events Configuration Settings

The CardValidator component is used to verify that a given credit card number is formatted properly, and could be a valid card number. Validating a card before actually submitting a transaction for authorization can reduce the fees that may be associated with invalid or declined transactions.

NOTE: What follows is a very short description of the component interfaces. For more information, please consult the help files that come with the respective package.

Remarks

Utilization of this component catches accidentally mistyped card numbers and allows buyers to re-input their number without having the transaction declined. It can also determine the type of credit card (Visa, MasterCard, Discover, etc) so that you can easily determine if the customer is presenting a payment type which you do not support. The component can also parse swiped track data and perform these same checks on it.

There are three checks performed on the customer's credit card information:


	The card number is checked for validity using the Luhn mod-10 algorithm.
	The type of the card (Visa, MasterCard, etc.) is computed from the card number.
	The expiration date is checked against the current system date.

The ValidateCard method explains these checks in more detail.
