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.
At first glance the numbers, while neatly arranged, appear to be completely random. But would it surprise you to know that there is indeed meaning and actual mathematical methodology to the way the numbers are sequenced? The process of generating real credit card numbers and validating them based on a proven mathematical formula is not only intriguing on an intellectual level and a hacker's dream, the carefully calculated way the numbers are ordered is actually quite beautiful and elegant when you come to understand how it works.www.moneybluebook.com
Validating Credit Card Numbers. 12 мая 2009 г. 2:17 by jonwood.When using ASP.NET to process online credit card orders, it is a good idea if you can perform some sort of validation on the credit card number before submitting it to your processor. I recently had to write some code to process credit card orders and thought I’d share a bit of my code.www.softcircuits.com
Before you actually encrypt your customer’s credit card numbers to a database or forward them to a merchant server, it’s a good idea to implement your own credit card validation routine. In this article we’re going to work through the development of a PHP class that stores the details of a credit card and validates its number using the Mod 10 algorithm. To implement the class we’ll create in this article, you should have access to an Apache web server running PHP 4.1.0 or later.www.sitepoint.com
