Q+ provides macro capability for mobile device cameras to view barcodes clearly on close up.
1. Peel off the transparent protective film from the sticky side of the lens.
2. Remove any external substance from the device camera, then attach the sticky side to the outer rim of the device camera
3. Press the lens firmly onto the device for 3 seconds to ensure attachment.
4. Q+ will greatly enhance the iPhone's capability for viewing smaller barcodes on close range.
If the lens's adhesive material gets dirty and loses its stickiness, rinse or wash it with clean water. Once cleaned and air-dried, it will recover its stickiness and can be reused over and over again.
