Card Guard: Payment Security Platform

Abstract

In today's age, we all use digital transactions most of the time. So the issue of safeguarding financial data is a big concern. Credit cards play a big role in the digital payments system. We need a system to know the accuracy of credit card numbers, which acts as a defensive wall against the rising trend of these fraud schemes. Our project aims on creating an impressive credit card validation system that is guarded by the very famous Luhn's algorithm. By the very capable use of the very powerful and dynamic programming language C++ and indulging the very powerful and indispensable data structures like arrays, linked list and stacks, we have aimed to strengthen the foundations of electronic and digital transactions safety. But the sole purpose of this credit card validation project is not only to tell about credit card validation but also about the type of card used. It aims to distinguish and differentiate between the different types of cards available on the market. It can detect various credit cards like Visa, MasterCard and multiple others which further increases the utility and importance in this modern world of finance and digital transactions._x000D_ At the core of this ambitious project lies the goal of an all including credit card validation system. The primary aim of this project is to guarantee the accuracy and precision of the given credit card details while at the same time revealing the intricate web of the issuing networks. The very foundation of this project lies on the very popular and renowned luhn's algorithm which is also known as the mod10 or modulus 10 algorithm. This inventor algorithm places the very vital role in validating the credit card numbers and also employing a series of mathematical operations which are very meticulously created to calculate a checksum this checksum acts as a litmus test which tells about the generousness and correctness of a credit card number which is according to a very particular rule set. Putting the luhn's algorithm to use with 100% accuracy and precision requires strategically
