Credit card generator
There was a mistake in the Javascript credit card generator, meaning it would not work on MS Internet Explorer or Opera. This has now been fixed, and I have tested it successfully on:
- Firefox 1.0.6
- Konqueror 3.4.1
- Internet Explorer 6.0
- Opera 8.5.2
The archive now also includes an example on how to use the Javascript version (which seems the most popular).
Command line Python program, PHP script, and Javascript script to generate valid (MOD 10) credit card numbers. Usefull for testing e-commerce sites. (Note: You can't actually buy anything with these). Should run on any platform.
This generates 13 and 16 digit VISA, Mastercard, Amex, and a whole bunch of others.
If you just need a bunch of numbers use the online credit card number generator. That page is generated by an online version of this script.
Fro the Python script, you will need Phyton . Once you have installed Python and extracted gencc.py from the archive, type 'python gencc.py' on the command line.
To use the PHP or Javascript scripts, you'll need to know a little bit about PHP or Javascript. In each case there is a method you need to call.
The ZIP and TAR.GZ below contain all three versions: The Python, PHP and Javascript files.
