About This Credit Card Validator

Advanced Credit Card Validator is a tool that helps verify credit card numbers using the Luhn algorithm (mod 10 check). This validator checks:

• Card number validity using Luhn algorithm
• Expiration date validation (accepts both 2-digit and 4-digit year formats)
• CVV code length verification based on card type
• Bulk processing of multiple cards with progress tracking

The validator supports all major card types including Visa, Mastercard, American Express, Discover, Diners Club, and JCB.
