Perl v1.02 Documentation

Quick Links

Security Notice: This is a historical archive. Modern credit card validation should use secure payment gateways (Stripe, PayPal, etc.) that handle PCI compliance. Never store or process actual credit card numbers on your server.

Overview

The Validator verifies credit card numbers using the Mod 10 Algorithm (Luhn Algorithm). It validates:

13 and 16 digit Visa Cards
16 digit MasterCards
16 digit Novus (Discover) cards
15 digit American Express cards

Important: This script only validates the format of card numbers using checksums. It does NOT verify if the card is active, has funds, or is stolen.
