I would like to announce card.js!

It is brand new library with following features:

• Credit card type detection based on IIN number. See more on wikipedia.
• Credit card type detection for full length card number
• Luhn algorithm validation. See more on wikipedia.

How to use it?

It can be loaded via a script tag in a HTML document for the browser (check examples/browser)

<script src='./relative/path/to/card.js'></script>

or as a CommonJS module.

For Node, put the card.js file into the same directory as the file that is requiring it and use

var card = require('./card.js');

or put it in a node_modules directory within the directory and use require(‘card.js’). See example in examples/nodejs.

The library is also available from the npm registry, so

$ npm install card.js

will install this library in a node_modules directory within the current directory.

Example of usage

card('4111111111111111').getType(); // output: visa
card('41').getIINType(); // output: visa
card('4111111111111111').isValid(); // output: true
