Quick Response codes, better known as QR codes, are those pixelated squares you see in restaurants, advertisements, stores, food packaging, business cards, airline tickets – you name it. Some developers would lead you to believe you need to download their app to scan them. Spoiler: Your phone can do that with built-in features.
QR codes were initially created to track automotive parts, but now they’re used for much more.
How many calories are in those fries? Where can you buy the outfit you see in an ad? How many miles can this car travel on a gallon of gas? A quick QR code scan can resolve all these questions and more. Think of this tech as a smart barcode.
