Credit Card Validation Script

[dchard]

Can anyone suggest a way to validate the credit card number? How to use it in coldfusion?
Thanks!!!

Below is an example of code that makes use of the automatic credit card validation in Coldfusion. My guess is that Coldfusion uses the Luhn algorithm. If you feel like doing the Luhn validation yourself, then there are lots of resources on the web to assist you, especially the Wikipedia on Luhn.

If your question is how to determine the card type, there is a CF_TestCardNumber tag in the exchange area.
