This article quickly showed me how easy it is to scan QR codes with both iPhone and Android phones. It explained step-by-step how to use the camera or special apps, even for codes on screens or in photos. I learned where QR codes are used, how to check if a code is safe, and what to do if scanning doesn’t work. The tips for better scanning were helpful, and I liked the safety advice. This guide made QR codes feel simple and useful in daily life. I highly recommend this article for anyone wanting to master QR code scanning.
