iBeacon is an interesting piece of location-based Apple technology and I started wondering about how useful it might be in a library context. Essentially (as this article from the Guardian describes) it is being sold as a micro-broadcast technology where transmitters can communicate with nearby smartphones. So there have been applications that have been proposed to allow shops to send you messages about special offers for example as you walk past, a sort of advertising sandwich-board I suppose.
But that technology might be interesting in a library context. You could see it directing you to where there is a public PC that is available for use, or telling you when you enter a library that something you have reserved is available for collection (or reminding you of things that are due for return). You could envisage it flagging up new resources as you walk round different sections in a library, or maybe tell you about library events related to that section. Browsing the fiction, maybe you might be interested in knowing about the ebooks that are available, or knowing about the book group that meets?
I wonder about how it might relate to the RFID tags in many libraries now and whether you could combine the technologies to use your phone to direct you round the library to find the book you wanted, and maybe to borrow it without ever needing to go near the self-service machines or a library checkout desk?
