About The Project

The Card Verify app is a React-based tool designed to validate and identify credit card numbers. It simplifies the process of determining whether a card number is valid and accurately detects the card type (Visa, MasterCard, Discover) based on industry-standard patterns.

The app ensures robust validation using the Luhn algorithm, checking for both card type compatibility and number integrity. It features a clean and intuitive interface, real-time feedback on user input, and dynamic updates for detected card types. The app demonstrates best practices in React development, modular architecture, and scalable deployment strategies.

Please check link for the sample credit card numbers.
