This technique is a common way to distinguish between legitimate numbers and numbers that have been entered incorrectly or otherwise on most credit cards and many government identification numbers. Anyone can use the algorithm because it is freely available in the public domain. Credit card companies then quickly adopted it. A team of mathematicians invented the LUHN formula in the late 1960s.

Luhn's method, commonly referred to as the modulus 10 or mod 10 algorithm, is a straightforward checksum technique used to verify a large number of identification numbers, including Canadian social security numbers, IMEI numbers, and credit card numbers.

Luhn's algorithm can be used to solve the problem. There are patterns in credit card numbers.Ĭredit card number must contain 13 to 16 digits.

If the credit card number entered is valid, the credit card type will also be printed. Credit card numbers entered by the user are generated along with a message indicating whether the card is valid or invalid. It verifies the authenticity of the card and the type of credit card by performing some basic operations and validations.

OverviewĪfter entering the credit card number, the system verifies its validity and determines whether it is a Visa, MasterCard, American Express or another form of card. Luhn's method is a straightforward checksum formula that can be used to verify a variety of identifications, including credit card numbers, IMEI numbers, and more, although it is most commonly used to verify credit card numbers. It uses the Luhn algorithm to determine whether a credit card number is legitimate or not. The C++ programming language was used to create a Credit Card Validator application that verifies the validity of a user's credit card number. It uses the Luhn algorithm to verify the credit card number and identify the type of credit card.
