RFID is not one technology. Almost all libraries today function with High Frequency (HF) tags and readers operating internationally at a frequency of 13.56 Megahertz However, RFID technology continues to evolve and there exists other technology options that might also be used as the basis for a library RFID system. One option receiving increasing attention is Ultra High Frequency (UHF) RFID. Some suppliers of RFID take the position that if library RFID systems were being developed for the first time today instead of a decade ago, UHF would be the logical technology platform. HF systems as used in most library systems worldwide are therefore seen by some to be legacy systems and not as part of the future of library RFID. Examined from a commercially neutral perspective are the issues, so that libraries may be in a stronger position to make their own decisions and take an active role in driving the development of RFID systems for libraries which incorporate the best technologies.
