Plenty of libraries are doing cool stuff with QR codes. We have added QR codes to our catalog records (public version to be released soon), even though we aren’t yet sure how they will be used.
We have also been playing around with different uses for small mobile whiteboards as ways to create some community and interaction.
Here, we ask a “This Day in History” question, and tape a QR code to the board for a resource that answer the question.
I expect plenty of patrons won’t know what the QR code is, which hopefully means they will ask.
From Wikipedia: “A QR Code is a matrix barcode (or two-dimensional code), readable by QR scanners, mobiles phones with camera, and smartphones.”
