Vannozzi D., Conti M., Buzzi M. DocSearch: UHF RFID Technology for Document Localization. In: ERCIM News, vol. 76 2009.
Radio-frequency identification (RFID) and sensor technologies are now enabling the Internet of Things. Ultra High Frequence (UHF) RFID readers and passive tags can be valuable tools for emerging pervasive services since they allow tags to be read at distances ranging from one-half to few meters, depending on antenna power, size and polarization. However, UHF has limits due to RF reflection, shadowing and absorption. Our experimental study investigates the feasibility of UHF RFID for reliable and efficient retrieval of archived documents.
