Android Credit card application

We need to create Classes for android application which will validate user input and creates token using our web service. Here is how it should work First of all there should be Card class Card class should accept following parameters: cardNumber, cardCVV, cardMonth, cardYear. aslo it should accept bunch of optional paramters such as addressLine1, addressLine2, billingAddresLine1, zip, nameOnCard and so on This class should have following methods: validateCardData which should validate all major card brands (Visa, MasterCard, American Express, JBC and Discover). Aslo one more core class needs to be created: CardApi. Which will have method createToken(Card card) It should accept Card class as a parameter. Please include word "kakashka" into your bid, so I can avoid scammers. Logic of createToken class: It should send all data to our web service (I will provide documentation to winner) as a result webservice rerurns a token which you should return from method.
