Using QR codes
Using QR codes is one of the easiest, most popular ways to have users view your content with their branded Google viewers, without any additional cost. They are not mandatory to use, but if you do have any videos or apps to show they come in very handy because they are very easy to use, and can be printed in the headsets along with your design, representing no extra cost.
They are also very simple to use, the user only needs to scan them with their phone camera to be directed to the content, place the phone on the viewer and they are done. To create your own QR code for free you can go to http://www.qrstuff.com/ and enter the desired URL. Once the QR code is generated, you can simply download it and place it onto your design, or send it to us so we can have our designers include that in the template.
They are not a prerequisite for using the units, they are only an addition you can opt for.
