11 <p>When a barcode is read, a beep sound will play and you'll see the results of the scan, a
12 description of what the barcode contains, and options to take action on the contents.</p>
13 <p>If you're having trouble scanning, make sure to hold the phone steady. If the camera is unable to
14 focus, try moving the phone further or closer from the barcode.</p>
