How Credit Card Validation Works: The Luhn Algorithm Type a credit card number into any checkout form and something checks it before the page even talks to the bank. That instant "invalid card number" message — appearing the moment you finish typing — comes from a checksum formula invented in 1954 by IBM scientist Hans Peter Luhn.
