When you look a credit card, there is a long string of numbers raised across the front which correspond to your bank and account information. Have you ever wondered what these numbers actually do and how they are used? If so, check out this infographic which breaks down the numbers on a credit card.

While you most likely don’t have any practical need for this information, it is really neat to understand the mechanics behind what these magic numbers are used for.
