Analysis and Design of a Rectangular Microstrip Antenna for RFID Applications

Several measures had been taken to ameliorate security technology at campuses using latest technologies available. Radio Frequency Identification (RFID) technology in campuses is mainly used for recording attendance which is further extended to activity monitoring and individual security. This research paper proposes a framework of RFID integrated solution for enhanced campus IT security including human, campus IT asset traceability, student’s valuables tracking, exam papers leakage security and issue authentic certificates. In order to meet the growing requirements of campus security system, the use of RFID technology in existing campus application has to be expanded where RFID technology certain performance issues may arise. Designing RFID enabled scalable and reliable applications is difficult due to managing and handling data banks generated by RFID tags, which further requires enhancing the entire IT infrastructure, inconvenient for Small and Medium Enterprise (SME) such as academic institutions having budgetary constraints. Therefore in order to take RFID campus implementation to the next level and create internet of things based applications, campuses have to embrace the concept of using the leading edge technology of cloud computing due to its both technological and economic benefits for supporting RFID technology.

Globalization of economy has broken trade barriers and improvements in information technology (IT) have given good greasing to the global trade by easing the flow of information between trading partners. The ability to utilize IT to ease trade has become an important issue. The current scenario of competition is not among companies, but among companies’ supply chain partners. Connective technologies have a great potential to integrate customers, information, and products across conventional supply chain boundaries, including management of manufacturing operations. Introducing Radio Frequency Identification (RFId) in supply chain has reflected a major technological advancement towards future gains by top business companies, hi this study, we examine the use of RFId technology in a supply chain (SC) and investigate its effectiveness and efficiency. The redesigned business process by implementing RFId technology to the members of a SC is investigated. The various factors affecting the SC, the challenges, and the solutions after applying RFId technology to a supply chain are also outlined. Practical applications related to tracking the movement of goods in diverse industrial sectors reflect the effectiveness of this technology. The analysis shows how pioneer implementers of RFId technology have improved the efficiency of SC and gained an edge over their competitors because of the reduced inventories. The initial pain of RFId implementation is outweighed by gains in long-term.

Radio Frequency IDentification (RFID) technology successfully integrates radio transmitter and receiver, small size memory space and control circuitry to remotely store and retrieve data via wireless RF transceiver. As low-cost RFID tag can be massively manufactured by semiconductor industry, new applications associated with RFID technology have emerged rapidly such as inventory tracking, book storage and management, and airport baggage handling. Generally an RFID system is composed of many RFID tags (or tagged objects), at least one RFID reader, and one backend application system with database. An RFID tag gains its operation energy from query signals that are radio waves transmitted by RFID reader. Once a tag responds the query with its stored information to RFID reader, usually a unique identity number or string, the RFID system can recognize the tag carrier and perform required business logic operation. As RFID technique is widely used in supply chain management, the corresponding RFID application systems are expected to process and manage large amount of tagged objects at a predefined period of time regularly. Therefore, for large-scaled RFID applications, tag reading throughput is very critical since it will affect the total data processing time. To measure tag reading throughput of a RFID system, two performance criteria are usually adopted: tag reading delay and reader energy consumption [5]. As RFID reader and tag always communicate over a shared wireless channel, it is very easy to have signal collisions during a normal tag identification process when multiple tags exist in reader’s interrogation area. Signal collision results in query or data retransmission and eventually increases communication overhead and time delay of tag identification. Hence, an efficient tag collision arbitration mechanism is very important and critical for RFID systems to achieve effective performance. Existing RFID tag identification schemes can be classified into aloha-based solutions [3, 10, 12-13, 16, 21, 23-24] and tree-based solutions [1, 2, 4, 6-9, 14-15, 17-20, 22]. In aloha-based schemes, a reader estimates the number of tags in its interrogation area and broadcasts the total number of timeslots to each tag. Then each RFID tag randomly selects its own timeslot to transmit its ID without knowing which timeslots have been selected by other tags. By distributing tag responses to distinct timeslots instead of getting all tag responses at the same time, aloha-based schemes effectively reduce the probability of signal collision. However, aloha-based schemes have tag starvation problem in which certain tags may not

There are many protocols proposed for protecting Radio Frequency Identification (RFID) system privacy and security. A number of these protocols are designed for protecting long-term security of RFID system using symmetric key or public key cryptosystem. Others are designed for protecting user anonymity and privacy. In practice, the use of RFID technology often has a short lifespan, such as commodity check out, supply chain management and so on. Furthermore, we know that designing a long-term security architecture to protect the security and privacy of RFID tags information requires a thorough consideration from many different aspects. However, any security enhancement on RFID technology will jack up its cost which may be detrimental to its widespread deployment. Due to the severe constraints of RFID tag resources (e.g., power source, computing power, communication bandwidth) and open air communication nature of RFID usage, it is a great challenge to secure a typical RFID system. For example, computational heavy public key and symmetric key cryptography algorithms (e.g., RSA and AES) may not be suitable or over-killed to protect RFID security or privacy. These factors motivate us to research an efficient and cost effective solution for RFID security and privacy protection. In this paper, we propose a new effective generic binary tree based key agreement protocol (called BKAP) and its variations, and show how it can be applied to secure the low cost and resource constraint RFID system. This BKAP is not a general purpose key agreement protocol rather it is a special purpose protocol to protect privacy, un-traceability and anonymity in a single RFID closed system domain.

Radio Frequency Identification (RFID) technology has been considered the “next revolution in supply chain management” (Srivastava, 2004, p. 60). Current research and development related to RFID focuses on the manufacturing and retail sectors with the aim of improving supply chain efficiency. After the manufacturing and retail sectors, health care is considered to be the next sector for RFID (Ericson, 2004). RFID technology’s potential to improve asset management in the health sector is considerable, especially with respect to asset management optimization. In fact, health expenses have increased substantially in Organization for Economic Co-operation and Development (OECD) countries in recent years. In Canada, the public health budget amounted to $91.4 billion (CAD) for the year 2005–2006 compared to $79.9 billion in 2003–2004 (CIHI, 2005). Moreover, the health care industry has been the focus of intense public policy attention. In order to curb this upward trend, the public heath sector in Canada is subject to strict budget constraints. Among the different alternatives for reducing expenditures, the improvement of asset management within the different health institutions appears to be worthwhile. RFID technology seems to be a viable alternative to help hospitals effectively manage and locate medical equipment and other assets, track files, capture charges, detect and deter counterfeit products, and maintain and manage materials. In other words, health care organizations would benefit particularly from RFID applications. The main objective of this study is to investigate the potential for RFID technology within one specific supply chain in the health care sector.B ased on a field study conducted in a large nonprofit hospital, this article tests some scenarios for integrating RFID technology in the context of two warehousing activities. We will first introduce the context of the health care sector and the current applications of RFID technology in that sector. The next section presents the methodological approach that was used in the study. The research findings and their implications are then discussed. Finally, some closing remarks are made.

Hospitals represent a significant part of healthcare systems and account for no less than 60% of the entire healthcare service in most of developed countries. Therefore, improving service in hospitals is an important element to the process of healthcare reform. Better use of resources, more consistent quality, and a higher service level are the keys to rationalise the huge expenditure in healthcare systems due to higher growth in demand. Even though massive spending has been directed towards hospital improvement in Ireland, services provided in Irish hospitals are ranked relatively low comparing to the other European countries. Growth of population, aging, European Union regulations, and demanding patients place more pressure on healthcare researchers to provide innovation solutions for Irish hospitals. In the last two decades, the use of technology had a significant impact on hospital performance in terms of responsiveness, quality, and management practices. Radio Frequency Identification (RFID) technology has been successfully implemented in a number of hospital systems in many developed countries. It is an emerging technology for applications such as managing and tracking patients, equipment, and drugs. Integrating RFID technology into hospital systems allows a dramatic enhancement in hospital efficiency and effectiveness measures to happen. This paper gives a comprehensive review on the up-to-date applications of RFID technology in hospital systems. It includes a classification of RFID applications at different areas of hospitals. Inclusive analysis of the impact of RFID implementation on the overall performance of the hospitals is presented. As new technology, this paper looks into the challenges and problems facing the management in employing the technology. Recommendations on potential impact of using RFID in Irish hospitals are discussed.

Radio-frequency identification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders. RFID stands for Radiofrequency Identification. The acronym refers to small electronic devices that consist of a small chip and an antenna. RFID technology, initially explored in the 1980s, became more accessible and widely implemented by the early 2000s.Libraries Libraries have long served as essential institutions for knowledge preservation and dissemination, traditionally relying on physical resources like books and journals. RFID systems consist of tags, readers, and integrated software. The integration of RFID technology represents a significant advancement in library services, enhancing efficiency and user experience. A notable development in this area is RFID (Radio Frequency Identification) technology, which has significantly enhanced library management and user experience. RFID technology utilizes radio waves to identify and track objects, such as library materials, automatically. The advent of digital technology has revolutionized libraries, transforming them into dynamic hubs of information and community engagement. RFID technology provides several benefits, including improved user experience, operational efficiency, cost-effectiveness, and optimized resource utilization. The evolution of library technology began with mechanical cataloguing systems, progressing to automated systems and Integrated Library Systems (ILS). In a library setting, RFID technology improves inventory control, self-checkout systems, and security. While challenges exist, the benefits of RFID technology in improving library operations and services are substantial. RFID technology in libraries offers significant enhancements across various operational aspects. The adoption of RFID in libraries has led to benefits such as faster inventory checks, reduced checkout times, and enhanced security against theft. This technological evolution encompasses digital cataloguing systems, online databases, e-books, and automated circulation systems, among other advancements. Self-checkout systems improve user convenience by allowing patrons to borrow materials independently. RFID also enhances security through anti-theft measures and enables real-time data collection for operational insights and personalized services.

The emergence of Radio Frequency Identification (RFID) technology provides the potential for vast and varied applications, bringing with it both promise and peril. RFID tags used as the medium for the collection and transmission of personal data, as well as tracing devices for the location of natural persons, open a Pandora's box regarding the privacy rights of individuals. The goal of this paper is to present the main privacy threats that arise from the widespread use of RFID technology and to illustrate the issues that have to be taken into consideration at the designing phase of an RFID application. The legislative initiative on RFID in the European Union (EU) will be presented and finally, a brief overview of the situation in the USA will be given.

The Radio Frequency Identification (RFID) tagging technology is being implemented by many businesses for production efficiency, logistics planning, supply-chain management, and other business related operations. However, there have been several implementation and control issues with the pervasiveness of this technology. This paper analyzes the security and privacy issues with the use of RFID in the commercial industry. It proceeds to assess the challenges with industry standardization among the RFID manufacturers at both the national and international borders. The Wal-Mart company is then used as a case study to assess its strategic use of RFID technology and its advantageously competitive positioning in light of its RFID technological renovation.

Safety, efficiency, and reliability are at the forefront priorities when it comes to planning and executing drilling and completion operations. As an industry moving toward exploration and development in far more demanding environments and is consequently driven to find new and innovative ways to optimize drilling and well completion costs; The integration of RFID technology into the oil and gas industry is an excellent approach which has resulted in reduction of risks, operating time as well as increased operational flexibility. The use of RFID technology as a technique for remote actuation of downhole drilling tools has proven to be very effective over the conventional mechanical (ball-actuated) drilling tools enabling operators to run multiple remotely activated drilling tools on same drilling BHA while also maintaining full through-bore ID. Radio-frequency identification (RFID) provides a game-changing solution across a broad range of disciplines to maximize efficiencies and reduce operating costs significantly. This paper reviews a field application in which an RFID-actuated circulation sub was deployed in a multiple-assembly tool string to drill and simultaneously log a 6-in. hole section for a well in Karachaganak field. The risk of downhole losses in a 6-in. horizontal section (∼1,200-m length) in Karachaganak field led to separate drilling and logging runs. The main driver of adopting RFID technology in this application was the inability to retrieve a logging-while-drilling (LWD) radioactive source (RA) and also pumping high-concentration lost-circulation material (LCM), should downhole conditions dictate activation of a circulation sub. RFID-enabled circulation sub to eliminate additional trips of the LWD tool, as the previously deployed mechanically-actuated circulating sub would not allow access to the LWD RA because of its limited post-activated inside-diameter (ID) size. This requires additional time for tripping operations to change out the BHA in case of downhole problems, such as stuck pipe and total loss scenarios. Introducing RFID-enabled tool provided full through-bore access enabling RA retrieval while keeping the option for multiple activations of the circulation sub as per operational requirements thereby enabling the operator to immediately eliminate the additional trip for the LWD tool. In this case study, no downhole losses were experienced; however, the RFID circulation sub served to boost hole cleaning once total depth was reached as this operation required high fluid-circulation rates for efficient cuttings transport, especially in the avalanche zone of the well. Additionally, the full through-bore flow provided by the RFID-actuated sub enabled the client to displace the well with a high flow rate and therefore save significant time and costs on fluid displacement The adoption of RFID-actuated circulation sub improved drilling performance by enabling the operator to complete the entire operation in a single run and saved 4 operational days. The main objective of the system was to drill and log safely and efficiently to the target depth in one run and achieve high flow rates to enhance wellbore cleaning.

Even invented and applied initially during the World War II, RFID (Radio Frequency IDentification) technologies [1] have attracted much attention recently. Precisely speaking, RFID technologies have been applied very widely in some proprietary or closed systems, for example, animal control [2], portal control (access badges), etc. in last decades. The main advantages of RFID application are, storing item data in an electronic way even for further update, data access by electromagnetic wave in a wireless manner, and allowing quick multiple accesses to RFID tags. Based on the diverse applications, different spectrum bands are allocated, for example, LF (125 134.2 kHz and 140 148.5 kHz) for animal control, HF (13.56MHz) for electronic ticket, and UHF (868 MHz-928 MHz) for logistics, etc. Most of the frequencies are located in the ISM (Industrial, Scientific and Medical) bands [1]. However, RFID was emphasized again mainly because of the need of supply chain [3]. By proposing a standard for the format of electronic data used for goods items, of which EPC (Electronic Product Code) [4] is an example, the products can be registered at once when they are shipped out from the factories in one country, and be released when they are checked out at the counter of a supermarket in the other country in the world. These products might have been transferred through Customs of many countries and carried by different traffic means. When being through these check points, the related data stored in the tags are updated. This is called “product tracking” and is to be carried out in an “Internet of Thing (IOT)” [5]. This Chapter is to have a review on the technology theme – how to provide low-cost RFID Tags, when RFID technology is to be applied into the logistics area where the RFID tags are supposed to be not re-usable and to be as “zero-cost” as possible. Generally speaking, there are three major parts composing a RFID Tag’s total cost, namely, antenna, chip and assembly for them. The cost of antenna, in addition to the design phase, is mainly dependent on the manufacturing process. Therefore, manufacturing process should be focused if antenna’s cost, then the tag, is concerned. This is the theme of this Chapter. Not like the other antenna applications, for example, wireless LAN or mobile phone, in which antennas need to be compliant to the end products’ appearance by following the market trend. In the tag antenna industry, on the contrary, it does not need to design or modify the tag antenna often. The tag antenna just needs to electrically match the chip used in the beginning of design. It is not necessary for tag providers to prepare a wide product spectrum in the market. Again, not like the mobile phone industry, RFID tag’s players just

Modern identification procedures such as radio frequency identification (RFID) are able to provide transparency in applications including supply chain, logistics and equipment management. The benefits of visibility and fast identification provided by RFID technology especially in supply chain management (SCM) reduce the risk of counterfeiting (Gao et al., 2004). There are two mainly ways in which RFID technology supports a visible and fast identification processes: 1) RFID allows for new, automated and secure ways to efficiently authenticate physical items; and 2) As many companies invest in networked RFID technology for varying supply chain applications, the item-level data can be gathered in any case (Lehtonen et al., 2006). Despite these benefits, RFID technology is still not widely implemented. The main reasons are, firstly, the difficult are, firstly, the difficult technical aspects of implementation resulting in high setup costs, secondly, growing security and privacy concerns. Our focus in this paper is to discuss the second reason for the low take-up of RFID technology, that is, security and privacy concerns. We argue that without applying maximum security and privacy, trustworthiness between supply chain partners will be minimal. As a result, the effectiveness and collaboration of traditional supply chain environment with RFID technology cannot be achieved. Given that humans cannot read the RFID tags on items and the tags themselves maintain no history of past readings, the challenge of security and privacy in this technology is related to the nature of RFID tags and their functionality (Juels, 2005). A retailer inventory that is labeled with unprotected tags may be monitored and read by unauthorised readers. The inventory data holds significant financial value for commercial organisations and their competitors. Once data has been accessed by unauthorised users, it can be cloned on empty tags, giving rise to the counterfeiting issue. Counterfeiting in the form of cloned or fraudulent RFID tags is the consequence of a lack of security measures and trustworthiness among the supply chain partners when RFID technology is used to automate their business transactions. Privacy violations stem from the fact that when goods are tagged, the manufacturers, retailers and consumers will be able to track the goods beyond point-of-sale (POS) because they have associated data. Even if the tags only contain product codes rather than unique serial numbers, a consumer’s taste in brands “constellation” can betray their identity.

RFID technology and its diverse applications: A brief exposition with a proposed Machine Learning approach

The purpose of the study is to evaluate the effectiveness of Radio Frequency Identification (RFID) technology in library management system and services in Bangladesh. This study followed survey and interview methods of data collection through a structured questionnaire. The population of study was all nine libraries in Bangladesh where RFID technology has been installed. The study reveals that all nine libraries are using RFID technology, namely, anti-theft detection Electronic Article Surveillance (EAS) gate, staff-work station and RFID tag. In addition to these, some of them are using kiosk, converter, level printer, book drop station, digital library assistance (DLA) and RFID smart card for entrance. The significance numbers of library users employ the RFID system and services and it is increasing gradually, but some of the RFID machines like level printer, book drop station and DLA are under-utilized because of lack of trained staff, patron’s doubt on new technology and less demand on using them in house-keeping library operation.

The purpose of this paper is to explore and describe the costs and process of implementing radio frequency identification (RFID) technology to manage and control the rotation of returnable transport items. Owing to the novelty of using RFID in logistics and supply chain management, in-depth case studies were conducted at two global firms in the retail industry to investigate how and why organisations implement and assess RFID technology. These case studies provide insights into how RFID benefits have been attainable in practice, and indicate that the cost of introducing RFID technology is not generally a barrier. As a result, this paper proposes an inductively derived stage model of the RFID implementation process. In this, implications for management are identified and discussed to guide managers in the process of implementing RFID technology.
