Paste a card number and this tool runs the Luhn (mod 10) checksum used by Visa, Mastercard, American Express and most other networks, answering "Valid card number" or "Invalid card number". Spaces and dashes are ignored. A pass only means the digits are well-formed, not that the card exists, is active, or has funds; the test number 4111 1111 1111 1111 passes.
