Credit Carder is an application that has been designed to help developers test their credit card validation code. CC generates perfectly valid numbers for ten credit card issuers. As well has generating numbers, it can also validate existing numbers and display the industry and issuer of said numbers.

The numbers generated by this application cannot be used to purchase goods as they are not tied to an account and will fail at the merchant process.

You can also use Credit Carder's generated numbers to have fun with phishers.
