Technically speaking, QrKeys are QR codes that contain special messages. Some QR codes, such as those for website and Wi-Fi networks, can be read by other devices, but others, such as lesson switching, are specific to LearnPad.
The QrKey Scanner
To activate the QrKey scanner, open the ClassConnect App and tap the QrKey icon on the menu bar at the bottom of the screen:
When the QrKey scanner has started you will see the view from the rear camera on the screen. Simply point the camera at the QrKey and hold it still. When the scan is complete you will hear a beep and the requested action will begin.
Make sure the QrKey is well lit and that the camera view is straight on (not at an angle).
Create and print your own QrKeys from the QrKey Management page.
