Consumer privacy is a major concern impeding the wide deployment of radio-frequency identification (RFID) tags in consumer market. To tackle this privacy issue, a simple and effective approach is proposed in this paper via adding one bit called ”physically changeable bit” (PCB) in RFID tags. The PCB bit can and only can be altered ”physically”. It controls whether RFID tags respond to queries s...

RFID systems allow fast and automatic identification of RFID tags through a wireless channel. Information on product items like name, model, purpose, expiration date, etc., can be easily stored and retrieved from RFID tags attached to items. That is why, in the near future, RFID tags can be an active part of our everyday life when interacting with items around us. Frequently, such items may cha...

In this article, we compare the different types of batterypowered RFID tags that are available today and explore several emerging wireless standards that are candidates for active RFID tagging. We also present an active RFID platform we have developed and a supply chain application implemented on that platform. INTRODUCTION Passive (battery-less) RFID technology has been the primary candidate f...

Proximity to Metal Metal presents a particular challenge to RFID. Most RFID tags show reduced performance when used near metal. Generic tags placed directly on a metal surface will likely not read at all. However, advanced RFID tags are specifically designed for use on or near metal. These tags typically have a special housing incorporating a gap of controlled width between the tag’s antenna an...

Our everyday environments may soon be pervaded with radio frequency identification (RFID) tags integrated in physical objects. These RFID tags can store a digital representation of the physical object and transmit it wirelessly to pervasive, context-aware applications running on mobile devices. However, communicating with RFID tags is prone to many failures inherent to the technology. This hind...

Radio Frequency IDentification (RFID) systems are gaining enormous interests at industry due to their vast applications such as supply chain, access control, inventory, transport, health care and home appliances. Although tag identification is the primary security goal of an RFID system, privacy issue is equally, even more, important concern in RFID system because of pervasiveness of RFID tags....

Radio Frequency Identification (RFID) technology has been available for more than fifty years. Nevertheless, only in the last decade, the ability of manufacturing the RFID devices and standardization in industries have given rise to a wide application of RFID technology in many areas, such as inventory management, security and access control, product labelling and tracking, supply chain managem...

This paper presents the design, implementation, and evaluation of the RFID Guardian, the first-ever unified platform for RFID security and privacy administration. The RFID Guardian resembles an “RFID firewall”, enabling individuals to monitor and control access to their RFID tags by combining a standard-issue RFID reader with unique RFID tag emulation capabilities. Our system provides a platfor...

This article reviews the use of implantable radiofrequency identification (RFID) tags in humans, focusing on the VeriChip (VeriChip Corporation, Delray Beach, FL) and the associated VeriMed patient identification system. In addition, various nonmedical applications for implanted RFID tags in humans have been proposed. The technology offers important health and nonhealth benefits, but raises eth...

Radio Frequency Identification (RFID) systems consist of readers, also called interrogators, and tags, also called transponders. This paper deals with RFID tags. Specifically, we deal with IC-based (integrated circuit based), passive, packaged RF tags with 64 bits of read-only memory. Today, tags cost upwards of 50¢, but there is great demand for low-cost RF tags. The specified target of 5¢ tag...
