Contains helper classes that I find useful every now and then.

This repository contains an implementation of credit card fault detection using Luhn's algorithm. Luhn's algorithm is a checksum formula used to validate credit card numbers, as well as other identification numbers. The algorithm is based on performing a set of arithmetic operations on the digits of a given number, resulting in a checksum value.

A simple Luhn Checker implementation, written for a school test.

Meant for education purpose. Fake credit card generator. Demo: https://bhuone-garbu.github.io/js-credit-card-generator/

This application is made using ReactJS, and it has a simple purpose, to check if the credit/debit card number is valid, or not, using Luhn Algorithms. It also has an additional feature to check the issuing agency of the card using the predefined IIN numbers.
