Wireless Item Label Locator

Our system, Wireless Item Label Locator, replaces the power‐consuming item tags with passive RFIDs which do not require batteries. Radio‐frequency identification (RFID) is an Hautomatic identificationH method, relying on storing and remotely retrieving data using devices called RFID tags or HtranspondersH. P [1]P The user will be guided by the sound, not from the tags but from the hand‐held remote locator, which will signal the direction and distance of the tag to the user. Our goal is to apply RFID technology to make a wireless locating system which helps vision‐impaired people to locate the item attached by a perticular RFID tag more easily.
