What exactly is a qr code and how does a square of pixels lead me to a certain website?
In: 5
Think of how a barcode when scanned give you a string of characters, usually numbers at the grocery store, but can also be a serial or part number that includes letters. A QR code is just the next iteration of that. It contains the website as it’s string as well as some instructions to the phone to open the browser and navigate to the website in the string.
