Our planet is covered in tiny squares filled with a curious arrangement of shapes that mean absolutely nothing to the naked eye. They are on posters, billboards, business cards, cereal boxes, and so much more. For the most part we ignore them, because there’s no reason to interact with these little squares unless specifically told to. They are called QR Codes, and once you figure out how to fit them into your life they can become an incredibly useful tool.
QR Codes are not a new technology, in fact they have been around since 1994 and were originally used to track components during vehicle assembly. Today you can find tiny QR Codes on components for tons of different things, as many companies still use this tracking method during assembly. For those of us who aren’t building a car, these little squares are used mostly for presenting links to websites and apps in a way that doesn’t require manual input.
