How to scan QR codes on Android

QR codes are all around us these days. Many offline products like flyers, some newspapers, brochures, posters, and billboards come with them to give you quick access to online resources without you needing to copy some long URLs. QR codes are also great for sharing contact information and Wi-Fi passwords. You need some software in order to read them, though. Luckily, these days most Android phones come with pre-installed solutions, so you don't have to download yet another app. There's also a lightweight website that does the job without trackers and ads, and some browsers even come with built-in scanners.
