If the predicted check digit and the real check digit are similar, then the card is validated.ĬlearTax offers taxation & financial solutions to individuals, businesses, organizations & chartered accountants The difference between the digit of the resulting sum at the units place and the number ten is the approximate test number. To decide whether a credit card number is valid, the sum of all the digits is first determined to find the units digit, but not the test digit. The Luhn algorithm is particularly useful as more transactions are performed online, where data breaches can be made easily.

The credit card validation process requires businesses and credit card companies to be able to quasi-instantly encrypt and decrypt confidential financial information about the card, issuer, and cardholder. However, since the algorithm is open for the public, it can be accessed and used by anyone in theory. After its development, credit card companies initially implemented the algorithm for use. How the Luhn Algorithm Works?Ī group of mathematicians developed the LUHN formula/algorithm in the 1960s. The algorithm is applicable to all major credit cards. If the total modulus 10 is equal to zero after working through the algorithm, then the number is valid according to the Luhn rule.Īlthough the algorithm can be used to validate certain identification numbers, credit card authentication is most commonly associated with it. The Luhn algorithm, also known as the Luhn formula or module 10, tests the sum of the numbers in the card number and indicates whether the quantities are equal to what is predicted or if there is an error in the sequence of numbers.
