RFID tags are tiny, inexpensive, inductively powered computers that are going to replace bar codes on many products, but which have many other uses as well. For example, they will allow smart washing machines to check for incompatible clothes (e.g., white shirts and red socks) and smart refrigerators to check for milk that is too old to be consumed. Subdermal tags with medical information are a...

Radio frequency identification (RFID) enables everyday objects to be identified, tracked, and recorded. The RFID tags are must be extremely simple and of low cost to be suitable for large scale application. An efficient RFID anti-collision mechanism must have low access latency and low power consumption. This paper investigates how to recognize multiple RFID tags within the reader’s interrogati...

RFID tags will exist pervasively in our daily life in a near future. In RFID systems, privacy and security are of critical importance to avoid potential tracking abuse and privacy violations. Many protocols have been proposed to address privacy and security issues in RFID systems. Physical attacks receive few considerations from the current research. Through physically attacks, attackers can ge...

Cloning of RFID tags can lead to financial losses in many commercial RFID applications. There are two general strategies to provide security: prevention and detection. The security community and the RFID chip manufacturers are currently focused on the former by making tags hard to clone. This paper focuses on the latter by investigating a method to pinpoint tags with the same ID. This method is...

Recently, the radio frequency identification (RFID) technology has gained significant attention. One of the important performance issues in RFID systems is to resolve the collision among responses from RFID tags from the viewpoint of wireless media access control. We consider two kinds of smart antenna systems to enhance the RFID tag reading rate, namely the adaptive array antenna and the multi...

This paper presents a method of using volume conduction for communication with implanted passive RFID tags. Based on electrode coupling, this method uses mainly electric field to transmit signal through tissue, and therefore can reduce the interference with metallic implants when RFID tags are attached to the implants. Exterior and interior electrodes are designed for efficient energy and signa...

This paper describes the first comprehensive benchmark suite for passive UHF RFID tags. These benchmarks give good indications as to how well RFID products will work in “real world” scenarios. We present benchmarks and give some experimental results, as well as key insights that these benchmarks have revealed about the nature of current UHF RFID tags on the market.

RFID technology arouses great interests from both its advocates and opponents because of the promising but privacy-threatening nature of low-cost RFID tags. A main privacy concern in RFID systems results from clandestine scanning through which an adversary could conduct silent tracking and inventorying of persons carrying tagged objects. Thus, the most important security requirement in designin...

We also describe tests wi...

RFID (Radio Frequency Identification) is a technology that uses radio frequency signals for purposes of identification and tracking of objects, humans or animals. In passive RFID systems, where tags reuse the energy radiated by the reader, coordination capabilities can be considerably limited [29]. This issue leads to conflicts or collisions between the transmissions of the different elements o...
