Literature Review on RFID Technology

REU Jackson State 2010

Abstract

Radio Frequency Identification (RFID) is one of the most exciting technologies that revolutionize the working practices by increasing efficiencies, and improving profitability. It is often presented as a replacement for today’s barcodes, but the technology has much greater possibilities, such as individual serial numbers for each item, and the possibility to read these numbers at a distance of several meters. They are simpler to deploy than wired solutions and these networks will enable improved understanding of processes and environments through continual monitoring of a larger set of parameters. In this project the evolution of wireless sensor networks will be presented, using RFID techniques with examples of implementations in payment of certain items without using the Universal Product Code (UPC). A virtual database comprising of RFID tags, antennae and experimental setup will be created and verified to make sure the proper amount is deducted from the correct item. The project I want to implement will fetch added features like speed in transaction, cost efficiency, low frequency of errors, etc. Another added feature will be the accuracy of the data recorded. Human errors will be resolved to the maximum thereby improving the efficiency of the system. The old-fashioned system of scanning items and manual entry can be removed and this method could be adopted to bring into action a more efficient system. The application should recognize all items in a shopping cart with the RFID tags and should communicate with an electronic reader that will detect every item in the cart and the sum will be calculated for all appropriate items. After the calculation, the reader will be connected to a large network that will send information on your products to the retailer. Your bank will then be notified and the amount of the bill will...
