How Does Our Online Card Validator Work?

Our online credit card validator has a very straightforward working. It utilizes a simple algorithm known as the Luhn algorithm to verify whether the credit card numbers are valid or not.

Another name for the Luhn algorithm is the “modulus 10” algorithm. In this algorithm, various calculations are performed on the provided number to ensure that the final result is divisible by 10.

The Luhn algorithm calculation involves the following steps:

Every second digit (starting from the rightmost end of the string) is doubled. For example, in this string 6011 6896 1656 2116, every second digit would be 6011 6896 1656 2116.

If a digit, upon doubling, becomes greater than 9, subtract 9 from it (for example, doubling 5 is 10, which means 9 will have to be subtracted from 10). To continue our example from above, this is what the string would look like 3021 3896 2616 4126

After that, all the digits in the string, including the doubled and undoubled ones, are added up. According to our example, this is what the calculation will look like 3+0+2+1 3+8+9+6 2+6+1+6 4+1+2+6

If the sum of all the numbers ends in 0, the Luhn algorithm is proved to be satisfied. But if the sum does not end in 0, then it means the Luhn algorithm is not satisfied. In our example, the sum of the calculation is 60, which means that this number satisfies the Luhn algorithm.

In the context of the Luhn algorithm, the checksum refers to the last digit of the credit card number. It is especially calculated and added to the string to make sure that it satisfies the Luhn algorithm.
