Tecnologia de identificação por radiofreqüência:fundamentos e aplicações em automação de bibliotecas

The Radio Frequency Identification Technology (RFID) is the newest technology that is being introduced with force in the libraries, for electronic management of the collection, implementation of automated check-in and check-out services, among others. The objective of this is to presents the principles of operations of the RFID technology, their components, the barriers for the adoption of the RFID technology and examples of implementation in libraries. The methodology used in this article was an extensive bibliographical and documental research about RFID technology. The results shows that the RFID technology are expanding more and more, at world level, in the extent of the libraries, for the facilities that the technology supplies. I conclude that the RFID technology is one of the technologies for libraries automation that they should be considered in the hour of updating the technological infrastructure for electronic management of the collection in libraries, considering his crescent adoption at world level due to the great advantages that offers.
