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.
Physical test cards from FIME don’t need to be programmed or configured, they are ready-to-use. They can be used to certify any type of terminal, even those with complex card paths such as ATM and CAT. They are suitable for multi-user environments such as testing laboratories where testers share the cards. FIME Test Cards are unique, they only need the Card Log Viewer - supplied with every card deck - and a card reader to retrieve and view test logs.www.fime.com

On satellite, however, where channels come and go apparently at random, there's often the odd test card or pattern to be seen - always electronically generated - and these introductory paragraphs are illustrated by some that I found knocking about recently in the Clarke Belt. So what is the purpose of test cards and why are they so rarely used these days?www.pembers.freeserve.co.uk
