Are people still using QR Codes?

For a client's site. We assume people know what they are, but it will be interesting to track its use. This one was created through my bitly account, so analytics are baked-in.

Suggestions I'm proud of:
1. Hiding it for displays smaller than 640px
2. Adding an href link to the png on the page— for the QR-curious. When they click, they'll be taken to the google map.
