We have a new digital signage system on the library main floor that allows us to create informational slides highlighting library services and events. Mounted on the wall near the library exit, it is viewable from most of the main floor, most importantly the circulation and reserves desk. I've posted images of the library (on a sunny, blue sky day), a simple floor directory, the weather (it's a changing feed), and a few slides for other offices located in the library. In an effort to generate some interest, I went to the Kaywa QR Code Generator, entered the library web site URL, and created as sign for the rotation.
Now we need someone with a web-enabled phone and bar code app to try out the QR code!
