Are there any recent innovations in this field with regard to radio frequency identification?
I’m not sure there is an awful lot that is new, as RFID has been used in libraries for more than a decade now. Perhaps one new development is the use of ultrahigh-frequency (UHF) technology. Last year, the Grand Rapids Public Library launched an RFID solution consisting of fixed and handheld readers, tags on all media, and software designed by the library’s IT department, in order to manage RFID read data and integrate it with the existing library-management system (see Grand Rapids Library Adopts UHF RFID Technology).
Most libraries deploy shorter-range high-frequency (HF) systems. Grand Rapids is believed to be the first library in North America to use UHF RFID, though some in Latin America had already adopted the technology. The main advantage is a longer read range, which helps when seeking a particular book on shelves. Given that the vast majority of libraries are employing HF RFID, it is unclear whether the use of passive UHF will become a trend or remain an anomaly.
