Modulus-10 algorithms for validation and generation

An interactive Python tool for validating numbers with the Luhn algorithm, generating check digits, and offering step-by-step explanations. Features include multi-number validation, file saving, and a user-friendly interface with rich, colorful output.

🔢 A Luhn algorithm (Mod 10 sum of values) for generating scan line check digits

The Luhn algorithm, also known as the "modulus 10" or "mod 10" algorithm, is a simple checksum formula used to validate various identification numbers such as credit card numbers, IMEI numbers, and more.

Function to check validity of Credit/Debit card using Lunh algorithm.

A credit card checkout interface built with Next.js 15, React 19, and TypeScript. This project features a credit card form with Zod validation, and a responsive UI powered by Tailwind CSS and ShadCN UI. It follows best development practices with ESLint, Prettier, and Husky, and includes CI/CD automation with GitHub Actions. 🚀
