Credit Card Generator

A valid credit card number has several fields and each of them has a meaning. For the technically inclined, this number complies to the ISO 7812 numbering standard. An contains a six-digit issuer identification number (IIN), an individual account identification number, and a single digit checksum.

The credit card numbers you generate on this page are completely random. When we say they are valid, we merely imply that they are a possible combination of characters which will validate when passed through the MOD 10 algorithm. You can also generate valid credit card numbers for specific Issuing Networks by utilising their particular prefixes. However, we do not provide you (obviously) with the correspondent verification code for these cards, as they are completely fake and made up randomly.

If you've ever found yourself trying to try a product online which required a credit card, even when you just want to take a look, you know why we made this. We believe there's no need to share such information with providers without the actual intent to buy stuff. Anyone can make a website with a form and require you to insert valuable and sensitive information which requires you to give up your privacy. This is a way to protect yourself in such situations.

The other reason we made this are programmers testing ecommerce websites, applications or other software. They usually need lots of fake data, and this is a very easy way to generate a bunch of valid credit card numbers in a split second. There's another tool for those times when you need to generate all other kinds of data.

After digging around, I still can't say for sure whether any, some, or all SD cards do this, but I do think it is possible. However, I don't believe that the caching would involve data larger than the erase block. To be really sure, I repeated the test using a 16 MB chunk instead of 64 kB.

All of the certificates on the test PIV Cards were issued from a test public key infrastructure (PKI), which was established to support the test cards. The PKI consists of a two-level hierarchy. In order to be able to validate the certificates on the test cards, it will be necessary to install the root certification authority (CA) from the PKI as a trust anchor in the software that will be validating the certificates.
