There has been a revolution in tracking and tracing of products and goods in the supply chain using passive radio
frequency identification (RFID) systems. Recommendations to the suppliers have been released to various major retailers and
government agencies after realizing the potential of RFID systems. This paper outlines some research done to identify a set of
parameters which can help us in comparing the performance of Ultra High Frequency (UHF) passive RFID tags to be set as
benchmarks. This paper is published on the notes of the above paragraph to provide a survey on radio frequency identification
(RFID) technology. Primarily the RFID tags were developed to eventually replace barcodes in supply chains due to their
advantages of being able to be read wirelessly and without line of sight, they contain more information than barcodes, and are
obviously more robust. The RFID technology did not stop at item-level tagging.
