QR codes and barcodes appear everywhere—on product packaging, event tickets, restaurant menus, and promotional materials. Your phone or tablet has a built-in camera that can read these codes and take you to websites, display information, or complete other actions. Understanding how to scan them on different devices removes the guesswork and lets you access the content quickly.
These articles cover the practical steps for scanning on phones and tablets, what to do when a scan doesn't work, and how to recognize when a code might not be safe to scan. You'll learn which built-in camera features do the work for you and when you might need a separate app instead.
