Checks a credit card number for validity.

You can use Credit Card Validation in one of two ways:

  • Without specifying the CreditCardType - If you pass in a CreditCardType of Unknown then we will automatically detect the brand of credit card from the number (e.g. Visa, Mastercard, American Express), and then use the relevant rules for validating that card against the number you have supplied. The CreditCardType will be returned in the result. This can be very useful for speeding up transactions as you do not need to ask the user to specify their CreditCardType.
  • Specifying the CreditCardType - If you pass in any CreditCardType other than Unknown then we will only check your card against the rules relevant for that credit card.

The system performs checks on the number range and a checksum calculation to ensure no typographical errors have been entered. It does not check with the bank that the card is live, has available credit and has not expired.
