Recently, the demand of the Radio Frequency Identification (RFID) system is increased for using in many applications such as personal access control, logistics, industrial process, product management, including identifying people, animals and products. The frequency band of the RFID system can be divided into four bands such as low frequency (125-134.2 kHz), high frequency (13.56 MHz), ultra hi...

The radio frequency identification (RFID) is a technology for automatic identification of items, particularly in supply chain, but it is becoming increasingly important for industrial applications. Unlike barcode technology that detects the optical signals reflected from barcode labels, RFID uses radio waves to transmit the information from an RFID tag affixed to the physical object. In contras...

RFID is currently considered a hot topic in the IT arena. It is described as major enabling technology for automated contact less wireless data collection and as an enabler for the real-time enterprise, a future vision of Enterprise Information Systems. But little is known about the perceived strategic importance of RFID among IT decision makers, current RIFD usage and areas of application or c...

Advances of sensor and RFID technology provide significant new power for humans to sense, understand and manage the world. RFID provides fast data collection with precise identification of objects with unique IDs without line of sight, thus it can be used for identifying, locating, tracking and monitoring physical objects. Despite these benefits, RFID poses many challenges for data processing a...

During recent years,RFID technology has a wide applications in many fields.Since singnal transmit by the radio frequency, it raises many security and privacy concerns. Ownership transfer of RFID tags is another requriement for RFID systems. During the life of tag, it may pass from manufacutrer to commercial agent, the ownership of tag need change correspondingly.Taking into account the natural ...

The security of RFID systems is a very important issue in the applications of RFID systems. Developing of authentication protocols is a general solution to * Corresponding author: e-mail: ejyoon@kiu.ac.kr (Eun-Jun Yoon) 3434 Il-Soo Jeon and Eun-Jun Yoon resist security attacks. However, since low-cost RFID tags have very limited hardware resources, it is not easy to develop an authentication pr...

RFID is a technology of automatic wireless identification and data acquisition. Meanwhile, the topic of RFID is a very popular issue in the field of technology. No Matter in software or hardware, there are many suppliers and demanders who invested a lots of resources to seek the efficiency and profit by using RFID technology. Therefore, many different solutions related to RFID application were ...

The integration of RFID technology and mobile smart device stimulates the daily increasing popularity of mobile RFID-based applications, which makes its way to become a new hot zone for research and development. Current RFID authentication schemes are not viable to use in mobile RFID environment. The authentication schemes result in computing load to the low cost tag and provide insufficient pr...

Radio Frequency Identification (RFID) is a relatively new technology. In recent years, it has been shown to be convenient and feasible in many applications. However, there are security issues which need to be addressed. Due to the wireless transmission of the RFID system, malicious people can gain the information in the RFID tags, and the user’s privacy is invaded. Although there have been many...

In this paper, we propose a new compact quasi-fractal shaped microstrip antenna that consists of a hexagonal patch as the main radiator and a complementary stacked patch as the parasitic element. The overall surface of the proposed quasi-fractal patch is about 55% lower than the conventional hexagonal patch. Using of stacked technique, the gain reduction of compression technique is almost compe...
