Libraries have been using radio frequency identification (RFID) technologies for years, enabling increased staff efficiency in the circulation and management of physical collection items, functioning essentially as a high-tech—and more expensive—bar code. Since it is tied to the computational power of smartphones (including location services), NFC offers some interesting possibilities for more innovative applications in libraries. I see considerable potential for library- and vendor-developed products and services that will enable more meaningful and productive interactions between library patrons and the content items and services in the physical library.
