How to scan QR Codes using iOS on iPhones and iPads
To scan QR Codes with the iOS 11 or later on iPhones and iPads open your camera and point it at the QR Code on the Plants Map sign or tag. You will see a notification asking if you want to visit the Plants Map page for that plant. Click the notification and the plant web page will open.
If this doesn’t happen, open your Settings and scroll down to the setting for Camera. There is an option to allow the Camera to read QR Codes.
If that does not work, or it is slow, you can still use an app. There are many free apps to do this but for the past few years, we have been recommending the app from Scan Inc. because it is very fast and it is continually updated for various phones and operating systems.
