RFID reader networks generate an abundance of event data every day. Those data are raw streams of RFID data, and do not bear any business meaning. A challenge issue in RFID middleware is the design of an appropriate mechanism for dealing with the mass data so that logical conclusions and state of the business can be derived. The paper investigates the issues related to effective RFID data management...
UHF band microstrip patch antenna for RFID reader with a center frequency of 867 MHz, as specified in Gen2 protocol European standards, is designed. Patch antenna is printed on FR4 material with dielectric constant of 4.55 with dimensions of 10times12 cm, from measurements at 867 MHz S11 is observed to be -22dB with an input impedance of 42.4 Omega.
Radio frequency identification (RFID) technology has become an important driver in the production and logistics activities of today's information-based industries and economies. With the innovative developments in information and communication technologies, companies focus more on how these changes can be implemented and promoted in order to improve their value-added processes. This paper presents...
In this paper we report the experiences from a pilot test in which users used an NFC-based catering service system. Primarily, the aim of this paper is to present the requirements for improving the functionality of the NFC-based systems. These requirements are based on the experiences from the catering service pilot described in this paper. The NFC-based catering service system was used by logistics...
This paper deals with an implemented system that contains advanced RFID-based control gates and smart connections to an OPC server that acts as central dispatcher. It proposes a scenario focused on the usage of more different control gates together with an integrated solution based on the state of the art industrial technology.
This paper describes a low power implementation of a secure EPC UHF Passive RFID Tag baseband system. To ensure the secure information transaction of the tag, traditionally the focus is on directly applying a low-complexity encryption engine. However, this approach could lead to the problem of known-plaintext attack (KPA). The attacker could make use of the known header to reveal the secret key. Our...
A novel technique for radio frequency identification devices (RFID) based on remote measurement of complex impedance at microwave frequencies is presented. The low cost read-only tags do not need semiconductor elements and can be implemented by printing a conducting pattern on a low cost dielectric substrate. Multiple tags are simultaneously illuminated by a chirped microwave signal with a bandwidth...
This article emphasizes on the efficiency, productivity and privacy of the integration of Radio Frequency Identification (RFID) technologies to mobile learning environments. It also mentions to the project that has been developed with the idea of creating a common RFID infrastructure that can be used with wireless/mobile information systems and making this infrastructure secure and reliable. The security...
We present a natural application of Radio Frequency Identification (RFID) technology for tracking and tracing high-value goods (HVG) in general. We cover in more detail such an application in the jewellery industry where large volumes of jewellery items are affixed with tamper-evident tags and scanned daily, thus lowering the risk for inventory shrink and deviation. Further, such application provides...
With the advancements in technology and science, electronics have been getting smaller and smaller, which enables researchers and scientist to weave the electronics and interconnections into the fabric. This new technology enables to establish a new concept called "electronic-textiles (e-Textiles)", which allows cost-effective and efficient solutions for various applications. In this paper,...
This paper describes the assembly of integrated circuits on flexible substrates in an industrial flip chip process allowing reel-to-reel production. Die bonding concepts to meet future demands for high-throughput solutions at low cost are introduced. Since the range of process parameters such as temperatures and bonding forces is closely linked to the properties of the substrates, an overview of different...
RFID is regarded as the future technology for the optimization of logistic processes. But there is a lack of methods and tools to support the logistic planer by identifying and implementing RFID applications. This is picked up by the research project "RFID in logistics" at the Technical University of Munich. The target is to point out possible RFID applications and appropriate components...
The objective of this paper is to investigate product shrinkage in the retail supply chain, and to consider how radio frequency identification (RFID) could act as a partial solution toward a retailer's loss prevention strategy. The research uses semi-structured interviews to collect data, and a qualitative content analysis to present the results. Given that the number of RFID deployments in the retail...
Customer orientation has been seen as a magic formula since 1980. Many companies invested a lot of money to change their IT systems in order to be more customer oriented, thus many different industries (retail, banking, airlines, insurance, hotels etc.) began with different CRM programs. Today nearly every company offers a different CRM or loyalty program. In the year of 2007, the problem is "differentiation...
In the current UHF RFID standards, there is no specific recommendation for the error correction capability. Whenever the CRC operation detects errors while receiving the EPC code from tags, the unidentified tags must participate in the next inventory round again. The identification rate then becomes significantly degraded. In this paper, we propose an error correction method on the return link for...
Reliability, security and privacy are the key concerns with RFID (radio frequency identification) adoption. While the mainstream RFID research is focused on solving the security and privacy issues, this paper focuses on addressing the reliability issues in general and detecting read rate failures in particular. We specifically consider the issue of detecting if some RFID tags are not read at all,...
Connecting microcontrollers, sensors and actuators by several communication systems is state of the art within the electronic architectures of process control. By now, the means of communication for process control is widely based on the fieldbus technology. While wireless communication is much talked about, there are still limited real products for the process control. Controller area network (CAN)...
An intricate step in the design process is validating the functionality of a design. As digital designs are getting more complicated, manual generation of efficient input stimuli used for design verification could sometimes get very cumbersome and tedious. In this paper we present a method for fully automatic input stimuli generation, applied in functional verification. The aim is to achieve maximum...
A portal provided with antennae could log Personal protective equipment (PPE) items and generate a warning signal when items are missing. Detection of PPE items before activating machines and technical equipment is also possible. Up to now such systems can detect the sufficiency of PPE but they can not distinguish between sheer presence and correct application.
The application of the RFID technologies to the university environment provides a more secure and effective examination process by reducing the waiting time to access the class and identifying the students that enter and exit the examination room in real time. This technology has particular relevance for universities with a high number of students that must ensure the entrance to an examination room...
