Distance Non-contact Radio Frequency Identification System Design and Realization

arjun — Sat, 08 Nov 2008 17:19:55 +0000

Abstract In this paper, we introduced a new design pattern of Distance Non-contact Radio Frequency Identification System, to overcome the inconveniency in most ‘jia-xiao-tong” systems, which usually require a contact or near-field scan. An efficient algorithm which is used to detect the entrance and exit was proposed to solve the problems of reflecting, refracting and data loss in the distance Non-contact RFID systems.

Implementation and Usage of Radio Frequency Identification (RFID)

arjun — Sat, 08 Nov 2008 17:16:46 +0000

Abstract Whether to solve specific business problems or comply with trading partner mandates, many companies are now engaged in pilot projects using radio frequency identification (RFID). RFID dramatically increases the potential for organizations to collect data about any tagable entity, which has implications for supply chain logistics, customer relationship management, health care systems, human resource management, and privacy/intellectual property policies. However, in many cases the adoption issues and the business case are not well understood for this emerging technology. This mini-track includes three papers on the Implementation and Usage of Radio Frequency Identification (RFID) technology in today’s organization and emphasizes the building of an on-going research tradition read more

An Introduction to RFID Technology

Abstract In recent years, radio frequency identification technology has moved from obscurity into mainstream applications that help speed the handling of manufactured goods and materials. RFID enables identification from a distance, and unlike earlier bar-code technology (see the sidebar), it does so without requiring a line of sight.1 RFID tags (see figure 1) support a larger set of unique IDs than bar codes and can incorporate additional data such as manufacturer, product type, and even measure environmental factors such as temperature. Furthermore, RFID systems can discern many different tags located in the same general area without human assistance. In contrast, consider a supermarket checkout counter, where you must orient each bar-coded item toward a reader before scanning it. So read more

The history of RFID

arjun — Sat, 08 Nov 2008 16:35:27 +0000

Abstract Whether we realize it or not, radio frequency identification (RFID) is an integral part of our life. RFID increases productivity and convenience. RFID is used for hundreds, if not thousands, of applications such as preventing theft of automobiles and merchandise; collecting tolls without stopping; managing traffic; gaining entrance to buildings; automating parking; controlling access of vehicles to gated communities, corporate campuses and airports; dispensing goods; providing ski lift access the objects to be managed, and operate automatically. The more complex devices (often called readers, interrogators, beacons) are more capable and are usually connected to a host computer or network. Radio frequencies from 100 kHz to 10 GHz have been used Download Share and read more

RFID: A Technical Overview and Its Application to the Enterprise

arjun — Sat, 08 Nov 2008 16:09:31 +0000

Abstract Radio frequency identification (RFID) has been around for decades. Only recently,however, has the convergence of lower cost and increased capabilities made businesses take a hard look at what RFID can do for them.A major push came when retailing giant Wal-Mart dramatically announced that it would require its top 100 suppliers to supply RFID-enabled shipments by January 2005. Though the bottom line story of that deployment has yet to surface, it does seem to support the inevitable movement of inventory tracking and supply chain management toward RFID. This article offers an RFID tutorial that answers the following questions What is RFID, and how does it work? What are some applications of RFID? What are some challenges and problems in RFID technology and implementation? How read more

RADIO FREQUENCY IDENTIFICATION

arjun — Sat, 08 Nov 2008 15:50:41 +0000

Abstract Radio Frequency Identification, or RF/ID, is a technique used to identify and track assets. The assets of interest depend on the industry in which it is used. It may be a rail car in the case of the railroad industry, a circuit board in manufacturing, or a passenger’s baggage in the airline industry. In each case, knowing where the asset is may be of value due to its cost, customer service improvement possibilities, or impact to the process in which it is involved. Historically, inventory control, regardless of market or industry segment, has been a major problem and financial burden. This holds true, whether one considers the “inventory” tracking required in a manuf acturing plant to meet its production schedule, or in a trucking firm trying to identify the read more
