How to scan QR Codes on Android devices
To scan QR Codes with the Android 9 operating system, 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, you are most likely using Android 8 or earlier and you will need a third-party QR code reader app to scan QR codes.
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.
