Generate Luhn-valid TEST card numbers for QA and development, or validate a card number. Test numbers pass the Luhn checksum and match a real brand format but are NOT real accounts, are linked to no one, and cannot be charged. Generate mode returns numbers for a brand (Visa, Mastercard, American Express, Discover); validate mode returns whether a number passes Luhn and its detected brand. Runs on Hopi's server; nothing is stored and no bank is contacted. Source: https://hopi.co.uk/test-card-number-generator/
