Instead of parsing through the string using tokens or some other nonsense we managed to validate our string using single lines of code. It includes first class support for potential validity so you can use it to present appropriate UI to your user as they type. It is designed as a CommonJS module for use in Node.js, io.js, or the browser. Regular expressions are quite powerful and if you can master them, they will save you a ton of coding time. Credit Card Validator provides validation utilities for credit card data inputs. $scope.mastercard = mastercard.test(value) ? "black" : "silver" $scope.amex = amex.test(value) ? "black" : "silver" But there is no common format in the debit or credit card numbering system. $scope.visa = visa.test(value) ? "black" : "silver" A Debit or Credit card number is a sequence of Digits with a specific formats. ntroller("CreditCardController", function($scope) The style information we’re going to use is as follows: The mastercard, visa, and amex variables that you see in the ng-style tag holds all the styling information for the active credit card. Safe for international and will NOT match (49) Switch debit cards.

There is, however, a few pieces of AngularJS code that we’ll see in a moment. Matches Visa Credit Card types 13 or 16 digits starting with 4 including Visa Credit Card, Visa ATM only, Visa Electron and Visa Delta.

Get a double of every alternate digit, if the double value is greater than 9 then take its remainder and add it to 1.
