It was invented by Hans Peter Luhn of IBM. It's used to determine if the credit card numbers have a logical pattern. If the numbers don't work with the algorithm, it isn't a valid credit card number.

The Luhn algorithm, developed by IBM engineer Hans Peter Luhn, is used for verifying credit card numbers. The algorithm is used to check the sequence of numbers on the card to ensure it’s valid.

Luhn algorithm implementation for PHP The Luhn algorithm, also known as the modulus 10 or mod 10 algorithm, is a simple checksum formula used to validate a variety of identification numbers, such as ...

The Luhn algorithm, also known as the "modulus 10" or "mod 10" algorithm, is a simple checksum formula used to validate various identification numbers such as credit card numbers, IMEI numbers, and ...

The Luhn algorithm is a mathematical formula developed in the late 1950s. The Luhn algorithm is widely used to validate the authenticity of identification numbers, such as Social Security numbers.

The Luhn Algorithm or Modulus 10 is one such device. Developed in the 1960s, it uses identification digits such as Social Insurance and credit card numbers to determine validity.

A payment gateway is the front-end technology that reads payment cards and sends customer information to the merchant acquiring bank for processing.

Plug a key into a hash table’s query algorithm, and it takes you directly to the item. This may not sound so extraordinary, but for enormous databases it can be a great time-saver. In 1953, Hans Peter ...
