RFID standards and applications are evolving for libraries. New standards like ISO 28560-4 for UHF RFID will improve interoperability. In the UK, the Library Communication Framework standardizes data exchange between library systems and RFID technologies. Applications are expanding from circulation to stock management and consortia services. However, privacy and security concerns remain as NFC capabilities in smartphones can now interact with library RFID tags. Libraries must complete privacy impact assessments in 2014 as required by the EU. Adopting new standards like ISO 28560-2 is recommended to ensure future interoperability.
