Abstract :
A smart shelf is an object identification system that uses Radio Frequency Identification (RFID) and LED indicators to quickly locate a specific object. The RFID is a powerful technology, which is vastly used for object identification. However, this system comes with challenges such as noise, interference from collocated RFID modules and higher power consumption for the passive RFID. This paper describes a system that uses an RFID module to harvest energy from an incoming radio signal both to power the circuitry in order to identify the object and to power an indicator LED. Also it describes how interferences between collocated tags can be minimized through the innovative use of aluminum and magnetic shielding.
