When you want to shop with a credit card, most of us enter our card number incorrectly. For example, if you type 44317 instead of 44371 in your card number, the system will ask you to repeat your number. This error is detected by the Luhn Algorithm. The test for the validity of a debit card number was invented in 1954 by Hans Peter Luhn, a scientist at IBM, before most people had a bank or credit card. The Luhn Algorithm is designed not to protect against malicious attacks, but to protect against accidental errors. The functioning of the algorithm is based on modular arithmetic, a mathematical technique developed by Carl Friedrich Gauss in the early 19th century.
How is te work Luhn Credit Card creating ?
First, type 16 digits of a debit card number intermittently. First underline the first number. Then do the same for the other tricks by jumping one. Then multiply all the underlined numbers by two. For example, let our card number be 4 4 3 7 1 2 1 4 5 6 1 8 9 1 7 3. When we get twice the numbers we have marked, we get 8 6 2 2 10 2 18 14.
Now add up all the numbers. In the meantime, what you should pay attention to is that if your number is two digits, you should collect the digits separately. So you should think 1+8 instead of 18. In this case, our total will be 8+6+2+2+1+0+2+1+8+1+4+4+7+2+4+6+8+1+3= 70. The full split of 70 to 10 indicates that the card is valid and no errors have been made. If you'd made a mistake, it wouldn't have been able to be completely divided.
American Express cards have only 15 digits. In that case, we're going to have to change our calculation a little bit. In our card number, we will mark the second digit on the left first. We'll keep marking it with another jump. The continuation of the process is the same. For example, our card number should be 3 7 8 2 8 2 2 4 6 3 1 0 0 0 5.
Sum of marked figures: (1 + 4) + 4 + 4 + 8 + 6 + 0 + 0 = 27 Sum of unmarked: 3 + 8 + 8 + 2 + 6 + 1 + 0 + 5 = 33.
The sum of the 2 sets of numbers is 60, again the number 10 is multiple. Which means we haven't made any mistakes once again. Let's give one last example. This time, you can have your Diners Club card. These cards have 14 digits and start at 300 or 305. For example, let our number be 3 0 5 6 9 3 0 9 0 2 5 9 0 4. Since the number 14 is even, we will apply the same technique as we did with the 16-digit card. Starting from the beginning, we marked the numbers in a jumper format. Now we're going to double these, and we're going to add up all the numbers that come out. If you follow the process, you'll reach 50, which means the card number you entered is correct.
