Dynamic framed slotted ALOHA (DFSA) protocol has been widely used in many RFID systems. According to the information from last frame (e.g. the number of idle, success and collision slots), DFSA dynamically adjusts the next frame size so as to reach higher identification efficiency. The process is known as tag estimation of DFSA. Similar to most existing tag anti-collision protocols, The DFSA in...

Mobile RFID is a new application that provides a valuable service to users with mobile communication. Current RFID authentication schemes are not viable to use in mobile RFID environment. Since unlike in regular RFID environments, whereas the communication channel between the server and the reader is assumed to be secure, the communication channel between the server and reader in the mobile RFI...

Certain businesses call for a high level of traceability to track high value products. This case study of City Healthcare,1 New Zealand, focuses on the complex management issues related to the initial decisions to use radio frequency identification (RFID) technology on such a product, instead of a barcode. RFID devices are effectively tiny memory storage devices that can be read and sometimes w...

Radio frequency identification (RFID) is a means of automatic identification that uses radio waves to detect, track, identify, and thus manage a variety of objects. The purpose of an RFID system is transmitting data from a portable device, called a tag, to an RFID reader to execute a particular application based on the tag provided identification or location information (Graafstra, 2006; O' Bri...

Successful object identification is the primary objective of Radio Frequency Identification (RFID) technology. Yet, a recent major study by Wal-Mart has shown that object detection probability can be as low as 66%. We propose the tagging of objects with multiple tags to address the fundamental issue of object detectability. We show that this strategy dramatically improves the efficacy of RFID s...

RFID technology has been widely utilized for the tracking and identification of numerous stationary and moving objects. One of the most challenging RFID applications has to do with the improvement in reliability, scheduling and efficiency of large‐scale transportation infrastructure. As an example, Radio Frequency Identification (RFID) technology in Ultra High Friency (UHF) frequen...

RFID (Radio Frequency Identification) technology is an automatic identification system consisting of a tag and a reader which can communicate with radio waves. Within the business processes it is possible to read and write the data from and into the microchip included tags from long distances. In this way, with lower costs more efficient process management and monitoring is provided. Today, RFI...

Radio frequency identification (RFID) is a technology that employs basic identifier of an object embedded in a chip, transmitted via radio wave, for identification. An RFID Card responds to query/interrogation irrespective of ‘Who’ holds the Card; like a key to a door. Since an attacker can possess the card, access to such object can therefore be easily compromised. This security breach is clas...

The use of Radio Frequency Identification (RFID) technology extends historically to the 1970’s, when the first commercial products emerged. The introduction of this technology motivated future research that sought to integrate RFID into various applications ranging from inventory control/monitoring to human/animal tracking. However, the practical significance of this technology was not fully re...

el presente trabajo se expone una introducción a la tecnología RFID (Identificación por Radio Frecuencia) que prometedoramente comienza a notarse como una alternativa viable para la captura de datos y el control de recursos varios en todos los sectores. En este mismo documento se incluye un análisis de las perspectivas propias y se culmina mostrando una aplicación práctica relacionada con el co...
