I recently facilitated a session in which the sponsor printed QR codes on the nametags. These codes mapped to resources and calendar dates related to our topic, but rather than delivering the information on paper, they shared it in this manner. Participants could then stick their used nametag on the back of a handout I supplied or instantly scan and download the resources they needed.
QR codes seem to be having a resurgence as more and more information is available in digital format only. I use QR codes on my handout cover page to link to an electronic version of the handout, the PowerPoint, and other resources related to the topic, but the nametag idea was new to me.
With almost everyone having a camera in their hand, you can provide depth without bulk or cost of printing, especially if you incorporate the code on something you are distributing anyway (like a nametag). Think about whether there is a way to tap into the trend and provide an easy way for people who want more information to easily access it.
