Application of RFID Technology in a Senior Design Course
This paper describes the design and implementation of a senior project based on RFID (Radio Frequency Identification) technology. The objective of the project, titled “Real Space Physical Object Tracking System (RSPOTS), was to design a complete RFID system that can physically locate an individual object from anywhere in the world via a secured Internet connection. By incorporating two or more customized RFID readers with location tracking capabilities (with an optional motorized camera system), any tagged object can be traced in a given location with the help of a network connection. The project uses a secured web site to display a 3-D (three dimensional) model of a given location, where a representation of the object is placed to represent its actual location. The paper also discusses the advantages and applications of RSPOTS. The major advantage of RSPOTS is that it can record and keep track of valuable products and visualize their movement over time with a motion-trail like display. A potential application of this system is efficient inventory control. Combined with a standard inventory system, RSPOTS can serve as an efficient tool to minimize yearly inventory variations and required adjustments for corporations, thus helping increase profits by curbing inventory losses. Furthermore, the paper explores the characteristics of “constructivist” and “deep learning” teaching/learning methodologies, inherent in teamwork, that allow students to gain new insights and competencies for enhancing their problem-solving and analytical thinking skills.
RFID is an electronic method of exchanging data using radio frequency (RF) signals. A typical RFID system consists of four elements: the RFID tags (transponders), the RFID reader, the antennas and choice of radio characteristics, and the computer network (if any) used to connect the readers. The RFID tag, the basic building block of the system, contains a microchip with an antenna. The microchip contains a radio receiver, a radio modulator for sending a response back to reader, control logic, memory, and power system. The tag can be powered by incoming RF signals (passive tag) or by an internal battery (active tag). The RFID reader also has its own antenna that transmits a pulse of electromagnetic energy to the tag and listens for tag’s response. The tag detects this energy and sends back a response that contains tag’s serial number and other required information. The RFID physical layer consists of actual radios and antennas that couple the reader to the tag. Most RFID systems use the unlicensed electromagnetic spectrum.1-2
RFID technology has been gaining momentum in recent years and is presently used in a number of applications, such as security systems, product tracking, production-line management, inventory control, product tracking, animal tracking, keyless entry, automatic toll debiting, and smart credit/debit cards.
