Radio frequency automatic identification system

摘要: A radio frequency automatic identification system detects targets which include a plurality of resonators. Information is attributed to the target in accordance with response characteristics target, such as resonant frequencies resonators present, and/or spatial locations within Preferred thin dipoles, may be metallizations on plastic film substrate. by fabricating disposed at encode information predetermined encoding system; alternatively, randomly disposed, and translation code applied convert particular format. Readers for use read near field radiating aperture illuminated source. Items encoded readable documents, credit cards, computer diskettes.
