Due to rapid growth of RFID system applications, the security and privacy problems become more and more important to guarantee the validity of RFID systems. Without introducing proper privacy protection mechanisms, widespread deployment of RFID could raise privacy concerns to both companies and individuals. As a fundamental issue for the design and analysis of secure RFID systems, some formal R...

A radio frequency identification (RFID) system is a special kind of sensor network to identify an object or a person using radio frequency transmission. A typical RFID system includes transponders (tags) and interrogators (readers): tags are attached to objects/persons, and readers communicate with the tags in their transmission ranges via radio signals. RFID systems have been gaining more and ...

Various smart antennas developed for automatic radio frequency identification (RFID) readers are presented. The main smart antennas types of RFID readers are switched beam, phased array, adaptive beamfsorming and multiple input multiple output (MIMO) antennas. New development in the millimeter wave frequency band60 GHz and above exploits micro-electromechanical system (MEMS) devices and nano-...

The Auto-ID Center is developing low-cost radio frequency identification (RFID) based systems with the initial application as next generation bar-codes. We describe RFID technology, summarize our approach and our research, and most importantly, describe the research opportunities in RFID for experts in cryptography and information security. The common theme in low-cost RFID systems is that comp...

Introduction Contactless RFID technology holds promise for object tracking, supply chain, smart payment and security management. Most RFID systems have their own unique hardware and software interfaces and are therefore are not readily available in the plug and play mode. At UCLAWINMEC, we have developed a unique RFID middleware platform and this platform is being implemented in software to mak...

The RFID (Radio Frequency IDentification) system is paid attention as a technology that can realize a ubiquitous environment. Each RFID tag has a unique ID code, and is attached on some object with the information of the objects. A user reads the unique ID code using RFID readers and obtains the information of the object. One of the important applications of RFID technology is the indoor positi...

Radio Frequency Identification (RFID) has become important to distribution and logistics operations due to current mandates by Wal-Mart and the Department of Defense. In order to meet these mandates, distribution operations have to re-layout their distribution facilities to accommodate these RFID systems. This transcript describes a layout algorithm that supports optimizing the design of RFID s...

For a dense RFID reader deployment, such as in a warehouse, where hundreds of readers will be positioned in a building, the interference between all these readers must be studied carefully to avoid disruption of operations. Strict RFID regulations and standards have been imposed, trying to address the problem of reader collision and also the problem of RFID devices interfering with other device...

Radio Frequency Identification (RFID) technology can be used to significantly improve the efficiency of business processes by providing the capability of automatic identification and data capture. RFID system must implement functions to posses the enormous event data generated quickly by RFID readers. The proliferation of RFID tags and readers will require dedicated middleware solutions that ma...
