Abstract
A radio frequency identification (RFID) system with separately located transmitters and receivers which lowers system cost. The system includes a plurality of transmitters for interrogating radio frequency identification tags attached to items on store shelves, a plurality of receivers separately located from the transmitters for receiving response information from the radio frequency identification tags.
Claims11
A radio frequency identification system comprising:
- a plurality of transmitters for interrogating radio frequency identification tags attached to items on store shelves;
- a plurality of receivers for receiving response information from the radio frequency identification tags, wherein the receivers are separately located from the transmitters;
- and
- a computer for controlling the transmitters and receivers.
A radio frequency identification system comprising:
- a plurality of transmitters mounted to a ceiling between store shelves for interrogating radio frequency identification tags attached to items on the store shelves;
- a plurality of receivers separate from the transmitters and mounted to the ceiling above the shelves and closer to the items than the transmitters for receiving response information from the radio frequency identification tags;
- wherein the transmitters number as low as about half of the receivers;
- and
- a computer for controlling the transmitters and receivers.
A method of capturing information from radio frequency identification tags attached to items on the store shelves comprising the steps of:
- providing a plurality of transmitters for interrogating radio frequency identification tags attached to items on store shelves;
- providing a plurality of receivers separately located from the transmitters for receiving response information from the radio frequency identification tags;
- activating the plurality of transmitters;
- and
- receiving the information stored within the radio frequency identification tags from the receivers.
A method of capturing information from radio frequency identification tags attached to items on the store shelves comprising the steps of:
- providing a plurality of transmitters mounted to a ceiling between store shelves for interrogating the radio frequency identification tags;
- providing a plurality of receivers separate from the transmitters and mounted to the ceiling above the shelves and closer to the items than the transmitters for receiving response information from the radio frequency identification tags;
- activating the plurality of transmitters;
- and
- receiving signals containing the information stored within the radio frequency identification tags.
A method of capturing information from radio frequency identification tags attached to items on the store shelves comprising the steps of:
- providing a plurality of transmitters mounted to a ceiling between store shelves for interrogating the radio frequency identification tags;
- providing a plurality of electronic shelf labels adjacent the items and containing receivers for receiving response information from the radio frequency identification tags;
- activating the plurality of transmitters;
- and
- storing the information in memories within the electronic shelf labels;
- and
- retrieving the information from the memories.
