Abstract

"MéTODO DE IDENTIFICAçãO POR RADIOFREQUêNCIA, E, MEIO LEGìVEL POR COMPUTADOR". Técnicas para detectar etiquetas de identificação por radiofreqüência (RFID) são reveladas. Por exemplo, é descrito um sistema de controle de saída que detecta remoção nao autorizada de artigos de uma instalação protegida. Uma série de antenas é configurada para produzir corredores de interrogação localizados próximos à saída da área protegida. Etiquetas RFID são anexadas nos artigos a ser protegidos. Cada etiqueta inclui informação que identifica com exclusividade o artigo no qual ela é afixada e informação do estado, tal como se a remoção dos artigos da instalação é autorizada. A leitora RF emite sinais RF através das antenas para criar campos eletromagnéticos dentro dos corredores de interrogação. A leitora emite energia RF de uma única porta a múltiplas antenas por meio de um divisor/combinador. Desta maneira, uma única leitora RF com apenas uma porta de transmissor/receptor interroga simultaneamente múltiplas antenas. Uma variedade de técnicas é descrita pela qual a leitora pode detectar a remoção de um artigo não autorizado.
