An RFID device (10, 56), comprising: a dual-input RFID chip configured to receive at least one high frequency-input and at least one ultra high frequency-input; or at least one high frequency-input RFID chip and one ultra high frequency-input RFID chip; a conductive sheet defining at least first and second portions, with an intermediate portion joining all of the portions; at least a first connection electrically coupling the respective first portion of the conductive sheet and the dual-input RFID chip or the at least one high frequency-input RFID chip; at least a second connection electrically coupling the respective second portion of the conductive sheet and the dual-input RFID chip or the at least one ultra high frequency-input RFID chip; and a third connection electrically coupling the intermediate portion of the conductive sheet and the dual-input RFID chip or the at least one high frequency-input RFID chip and the at least one ultra high frequency-input RFID chip, wherein the first portion of the at least first and second portions of the conductive sheet defines a multi-turn high frequency antenna having one or more disruptions in the conductive sheet positioned between and/or defining adjacent turns of the multi-turn high frequency antenna, the second portion of the at least first and second portions of the conductive sheet defines a first radiating arm of an ultra high frequency antenna, and the one or more disruptions in the first portion of the at least first and second portions of the conductive sheet are configured to reduce the conductivity of the conductive sheet at the location of the one or more disruptions to a low enough level so as to direct a high frequency current around the turns of the multi-turn high frequency antenna rather than across the one or more disruptions, while allowing an ultra high frequency current to flow across the one or more disruptions, thereby resulting in the first portion of the at least first and second portions of the conductive sheet defining a second radiating arm of the ultra high frequency antenna. a dual-input RFID chip configured to receive at least one high frequency-input and at least one ultra high frequency-input;
