Executive Summary

In this paper we are going to analyze the RFID technology, because in past few years the RFID technology has stimulated from murkiness straight into the main stream applications which enables the organization to speed up the process of manufacturing and handling of materials goods. The RIFD technology enables the identification of certain objects from distance. The tags used by RFID are able to support much larger set of unique codes as compare to the size of codes that could be supported by bar code technology. Along, with that the RFID tags can incorporate an additional amount of data including the name of the manufacturer, and type of the product etc. Furthermore, the RIFD systems have the ability to discern an extensive amount of tags that located inside the same store. RFID systems can be effectively used in various fields. Among them, automation, control the authenticity of objects, inventory, fixed assets and goods, tracking of the supply chain for logistics companies, the management of business processes in retail. No less effective RFID can be used in the medical field, libraries, access control systems and loyalty. In RFID systems, the reader and tag communicate using radio waves, meaning they do not require physical contact or line of sight, as with barcodes. The reader transmits radio signals continuously via its antenna. There are several amounts of benefits that are associated with the RFID systems benefits such as: RFID tags let you know when a product has been stolen, and offers the ability to know where it is located. Also, if the RFID system is combined with other technologies such as paging systems, camcorders and other elements associated with monitoring, it becomes a useful tool to prevent theft in retail stores. However, there are also some drawbacks of this technology such as: reader collision which occurs due to the overlapping of two or more signals, and tag collision which occurs during simultaneous queries.

Introduction

In the last 20 years were trading units of products (pallets, containers, packages, single products) labeled with barcodes, the current trend is definitely toward identification by Electronic Product Code (EPC) and RFID technology (Radio Frequency Identification). RFID is a technology for the identification of objects by radio (radio frequency, RF). What has been in immobilizers used in access control systems and waste management will be used in the future in the movement of goods. Modern manufacturing methods enable very thin chips that store EPC numbers, and so the world can be uniquely identified. EPC (Electronic Product Code) is a 96bit code, which will replace the 13digit UPC bar code. Occasionally one hears that RFID label displace barcodes on product packaging. And sure enough, there where pallets, boxes and containers are moved on a large scale, for example, in storage or behind the store shelves, is still working hard with normal barcodes. Here, RFID has prevailed. But in the areas where consumer access to individual articles, the ...
