Credit Card Validator

Abstract

We use stacks in this project which play a very important role in carrying out the various complex calculations which are required by the luhn's algorithm. Stacks also provide an impressive and well-structured approach and it allows streamlining operations on the numbers which are used in the algorithm's calculations. The principal of last-in-first-out (LIFO) in itself is a very great way to do the sequential and iterative nature of the algorithm which enhances the decision and reduces the time which we require in processing the digits of the credit card. His credit card validation project has an aim which includes multiple functionalities which serve as solving very crucial purposes. The main function is around the careful process of validation and carefully observing the given credit card numbers against the specific rule set of the luhn's algorithm. The algorithm which can be used as a litmus test, very clearly categorizes the given input would be valid or invalid based on the different guidelines that are provided. But far from just validation the system also tells you about who is the cards issuer. With this functionality there is an added capability in which we can tell about the complications of the various major card networks such as MasterCard or Visa. Having this involves a yet intrinsic approach of matching the patterns and doing word to word analysis of the various characters that are used specifically and the prefixes that are also used. By being able to tell these answers the system very efficiently tells and puts the category of the cards issuer which not only increases the functionality but also plays a role in managing and telling about the various information of the credit card. The project's implementation is around user-centric interface which is made to make the validation process easy for the users which the users can trust. Users work with the friendly prompt which invites them to put in the car details trustingly.
