jQuery Credit Card Validator detects and validates credit card numbers. It’ll tell you the detected credit card type and whether the number length and Luhn checksum are valid for the type of card.
The latest stable version is always in master branch. If you need previous versions, you’ll find them on the releases page.
Do not use any branches other than master. Branches like release/1.0 are development branches and they will most likely be broken.
For instructions see the official jQuery Credit Card Validator homepage.
