If you are with your laptop:
Open the QR Code reader on your phone.
Hold your device over a QR Code so that it’s clearly visible within your smartphone’s screen.
1. The phone automatically scans the code.
On some readers, you have to press a button to snap a picture, not unlike the button on your smartphone camera.
2. If necessary press the button.
Presto! Your smartphone reads the code and direct you to the appropriate App Store to download your [email protected] app.
