Assessment of RFID Technologies and the EPC Standard

The underlying technologies and concepts of Radio Frequency Identification (RFID) technology have been in existence for decades, with the last several years seeing an accelerating pace of innovation both at the core technology and application levels of this area. In addition, the emergence of Electronic Product Codes (EPC) have made it possible to capture, analyze and predict the performance of complex organizational processes and strategies (Banks, Buckley, Jain, Lenderman, 2002). Combined, these developments and their use are building a strong business case for the adoption of RFID technologies to solve complex processes, problems and attain strategic objectives.

Radio Frequency Identification is based on radio frequency waves that operate at predetermined frequencies to identify and communicate packets of data from the transponder to the reader or receiver (Banks, Buckley, Jain, Lenderman, 2002). What differentiates one type of tag from another are the frequencies used for communicating between the transponder and receiver. The transponder is embedded in a common RFID tag and includes a micro-chip which stores and communicates the EPC-formatted data via antenna to the receiver. The most common configuration fo RFID system includes an RFID tag, reader and host processor (Trunick, 2005). There are passive tags (which are lower cost due to not having a power source) and active tags (which have a power source and operate at higher frequencies). An example of a relatively simple RFID tag is shown in Figure 1, Passive RFID Tag which illustrates where the micro-chip containing the UPC code is in addition to the location fo the antenna (Hartman, 2006).

RFID tags also have a specific EPC Tag Class designations as well, as the EPC taxonomy of codes and data structures bring greater intelligence into the enterprise-wide workflows they are included within. The EPC class codes range from Class 0 to Class 5, each differentiated for a specific task and workflow requirement (Shutzberg, 2004). Figure 2, EPC Code Analysis, indicates how each EPC Code is differentiated from the other, ensuring accuracy and fidelity of each tag class and type overall.

RFID continues to evolve as a standard and is gaining momentum as EPC is providing more data for analytics and assessment of process performance than has ever been the case in the past.

State of RFID implementation

Having progressed from being a technology primarily used for large-scale military logistics applications including managing complex, difficult-to-track assets across diverse geographic regions, RFID today is pervasive in… [END OF PREVIEW] . . . READ MORE
