How do I scan a QR code on a wedding invitation?

Most modern smartphones can scan QR codes directly through the camera app, without needing a separate app. Open your camera and hold it over the code, making sure the code is fully inside the frame. Keep the phone steady for a couple of seconds. You should see a notification or a link appear at the top or bottom of the screen. Tap that notification to open the wedding website or RSVP page. If nothing happens, check that the code is not damaged, smudged, or too small. Move the phone closer or further away until it focuses. Also, make sure you have enough light, as a dim room can make scanning difficult. If your camera app does not recognise the code, you can try a QR scanner app, but most phones now have this built in. Once the link opens, you can browse the website or fill in the RSVP form. If you are having trouble, ask the couple or a guest for help, or look for a website address printed on the invitation as a backup.
