Abstract

Un método y sistema para determinar la ausencia o presencia de artículos en una zona de interrogacion de RFID. Al menos un lector de RFID transmite senales de interrogacion en una zona de interrogacion. Cada lector de RFID transmite senales de interrogacion que tienen una cantidad de energía de radiofrecuencia directa y recibe senales de respuesta desde los artículos en la zona de interrogacion que tienen una cantidad de energía de radiofrecuencia reflejada. Un circuito de deteccion determina la presencia y ausencia de artículos dentro de la zona de interrogacion basándose, al menos parcialmente, en la cantidad de energía de radiofrecuencia reflejada.
