## What it is
A jQuery plugin that detects credit card types and validates card numbers using length and Luhn checksum checks. It runs validation on form fields as values change or on demand, returning the detected card type and validity.

## Use cases
- validate credit card numbers in a payment form
- detect whether a card number is Visa, Mastercard, Amex, or Discover
- check Luhn checksum validity of a card number as the user types
- add visual feedback classes to card input fields based on validity
- validate card numbers before submitting an order form

## When to choose
- you have a jQuery-based checkout or payment form needing client-side card validation
- you want lightweight card type detection and Luhn validation without a full payment SDK
- you need real-time validation feedback on a card number input

## When to avoid
- your project does not use jQuery
- you need actual payment processing or card tokenization (use Stripe/Braintree instead)
- you need server-side validation or PCI-compliant handling
- you need validation of modern card schemes beyond the supported set
