QR codes are everywhere, and this article shows how easy it is to scan them with an iPhone or Android. I learned that most phones have built-in QR scanning in the camera app, and there are simple steps to follow for both devices. The article explains why QR codes are so popular, gives real-life uses like menus and payments, and even shares tips for better scanning. I liked the advice on making your own QR codes and using them at events. This guide is clear, practical, and makes scanning QR codes feel simple and useful.
