>What exactly is a qr code and how does a square of pixels lead me to a certain website?
A QR code is just regular text encoded in a way that is easier to read by an automated system. Think of it as a special font.
If that text happens to be a URL then whatever scanner you use to read the QR code can pass it on directly to your browser if you have set it up that way.
**EDIT**: But don’t do that. Setting anything to “automatically open any URL” is not very secure.
Do you know how binary works? A bunch of 1’s and 0’s, which your phone/computer interprets into various kinds of data?
A QR code is binary in the form of squares that are either black or white. There’s some guidelines to let the computer know where to start reading, what format the data is supposed to be, and some things that make it easier for a camera to get the exact interpretation, but that’s what it is at it’s most basic.
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.
