A credit card mass checker tool that validates credit card numbers based on the Luhn algorithm

Interfaz para activar tarjetas de crédito online.

Card Validator is a simple tool for validating if a card number is valid or not. It checks the card number format and the Luhn algorithm to see if the card number is valid.

Es una web app llamada VITANI donde el usuario podrá comprar accesorios para animales. Al momento de elegir el producto y darle click a "comprar" se pide el número de tarjeta de crédito para validar y continuar la compra.

This is my very first Vanilla JS, HTML and CSS project. It's a card validation algorithm intended to women over 50 y/o.
