Credit Card Validation Component

To give you an example of how you might use the Credit Card Validation Java Component, I have build this very simple application.

In this application you can validate any VISA credit card number. The application will do the following:

Make sure there are only digits in the number (spaces and hyphens are ok)

Verify that the number is a VISA

Check that the number is of the correct length

Perform a checksum to check for validity

If any of these steps fails, a message will be displayed.

Commercial Version

In the full commercial version you can validate all the major credit cards: VISA, MasterCard, AMEX, Discover, Diner's Club, enRoute, and JCB. In addition the methods provided in the commercial version have more than one way of calling them, while the demo version usually has only one.
