Introduction to RFID in supply chain

Prof. John Clendenin, Chief Executive Officer of IC Logistics, U.S., has said “INDIAN ENTERPRISES must draw up plans to incorporate Radio Frequency Identification (RFID) technology to meet emerging global requirements, failing which they will find it difficult to do business in a trans-national framework in the coming years.”

Research firm Gartner, Inc. states: “The use of RFID to capitalize on data flow in global supply chains could be one of the most-significant developments since enterprises first explicitly recognized the importance of information flow in the supply chain.”

Squeezing cost and inefficiency out of the supply chain has been one of the recurring mantras of the industrialized world for the past 50 years. The concept, as we would recognize it, has its roots in the Toyota Production System (TPS) of the 1950s and has been refined and improved significantly over the years to the point where one might expect that the most sophisticated devotees today have optimized their supply chains.

The journey towards perfection, however, never ends. In the very near future, the adoption of sensor-based Radio Frequency Identification (RFID) technology will allow the creation of the real-time, sensor-connected manufacturing plant. By adding RFID tags to every product, tool, resource and item of materials handling equipment, manufacturers will be able to get better demand signals from customers and the market. RFID will have a significant impact on every facet of supply chain management—from the mundane, such as moving goods through loading docks, to the complex, such as managing terabytes of data as information about goods on hand is collected in real time.

RFID is a technology that uses radio waves to identify objects automatically. The applications of RFID have been found in all kinds of consumer products and industrial equipment. RFID, which has the same purpose as a bar code, provides a unique identifier for the objects. The most significant advantage of RFID over the bar code is that the RFID does not have to be positioned precisely and can function approximately 20 feet from the scanner. RFID technology not only can help businesses satisfy customer requirement, but also increase productivity to stay competitive.

RFID technologies hold the promise of closing some of the information gaps in the supply chain, especially in retailing and logistics. As a mobile technology, RFID can enable “process freedoms” and real-time visibility into supply chains. RFID promises to revolutionise supply chains and usher in a new era of cost savings, efficiency and business intelligence. The potential applications are vast as it is relevant to any organisation engaged in the production, movement or sale of physical goods. This includes retailers, distributors, logistics service providers, manufacturers and their entire supplier base, hospitals and pharmaceuticals companies, and the entire food chain.


The technology in brief:

RFID is a generic technology concept that refers to the use of radio waves to identify objects(Auto-ID Center, 2002). RFID tags have both a microchip and an antenna. The microchip is used to store object information such as a unique serial number. The antenna enables the microchip to transmit object information to a reader, which transforms the information on the RFID tag to a format understandable by computers.

(The system as shown in Figure 1 consists of an interrogator or a controller, one or more transponders or tags.)

Brilliant Prof. John Clendenin! Supply Chain Management Services have introduced Radio Frequency Identification technology to meet emerging global requirements in India. Radio Frequency Identification technology can enable process freedoms and real-time visibility into supply chains which can easily helps in saving much costs during their production.
