Jun 16, 2015 · Let’s take a closer look. However, it has been suggested that not all letter/number combinations might appear (eg. So, how exactly do hackers steal gift cards, and why is e-commerce failing miserably at stopping them? Let’s break it down. The Luhn algorithm or Luhn formula (creator: IBM scientist Hans Peter Luhn), also known as the " modulus 10" or "mod 10" algorithm, is a simple check digit formula used to validate a variety of identification numbers. I'm wondering what the most secure way of generating these gift card codes are. The Luhn algorithm works by applying a mathematical formula to the card number digits. Here's a step-by-step breakdown of the Luhn Algorithm: We would like to show you a description here but the site won’t allow us.
