CardValidator Class

Properties Methods Events Configuration Settings Errors

The CardValidator class 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.

Syntax

class inpay.CardValidator

Remarks

Utilization of this class 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) to easily determine if the customer is presenting a payment type which you do not support. The class 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 validate_card method explains these checks in more detail.
