Applications include inventory tracking, prescription medication tracking and authentication, secure automobile keys, and access control for secure facilities.This book begins with an overview of UHF RFID challenges describing the applications, markets, trades and basic technologies. It follows this by highlighting the main features distinguishing UHF (860MHz-960MHz) an 410 0$aFocus series in waves. 606 $aRadio frequency identification systems 608 $aElectronic books. 615 0$aRadio frequency identification systems. 676 $a025.1 676 $a621.3841 676 $a621.3841/92 700 $aLaheurte$b Jean-Marc$0855866 702 $aLaheurte$b Jean-Marc 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910139143403321 996 $aUHF RFID technologies for identification and traceability$91910723 997 $aUNINA
