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.
