RFID
Radio frequency identification (RFID) uses radio waves to identify physical objects. An RFID system has three main components: tags attached to objects, readers that can read or write tag data, and backend databases that correlate tag data with objects. RFID has a long history including early military applications for identifying friendly aircraft. Commercial uses now include supply chain management, inventory control, and retail checkout. However, RFID also raises security and privacy concerns due to potential hacking of tags.

An Ethical Exploration of Privacy andRadio Frequency Ident.docx
An Ethical Exploration of Privacy and
Radio Frequency Identification Alan R. Peslak
ABSTRACT. This manuscript reviews the background
of Radio Frequency Identification (RFID) as well as the
ethical foundations of individual privacy. This includes a
historical perspective on personal privacy, a review of the
United States Constitutional privacy interpretations, the
United Nations Declaration of Human Rights, European
Union Regulations, as well as the positions of industry
and advocacy groups. A brief review of the information
technology ethics literature is also included. The RFID
privacy concerns are three-fold: pre-sales activities, sales
transaction activities, and post-sales uses. A proposal to
address these privacy concerns is detailed, generally based
on past philosophical frameworks and specifically on the
Fair Information Practices that the Federal Trade Com-
mission has outlined for the electronic marketplace (e-
commerce). It is proposed that by application of these Fair
Information Practices, the major privacy issues of RFID
can be addressed.
KEY WORDS: Agency theory, deontological, electronic
commerce, ethical framework, fair information practices,
information technology ethics, privacy, radio frequency
identification, RFID, teleological
Purpose of the study
Radio frequency identification (RFID) is a tech-
nology that allows every manufactured item in the
world to be uniquely identified. Essentially, it is an
inexpensive passive electronic device that allows for
the transmission of a distinctive signal from any
product or artifact in which it is embedded or at-
tached. This technology represents unique chal-
lenges of privacy as well as monetary and security
benefits. This manuscript reviews privacy and the
issues associated with RFID including historical
perspectives, deontological and teleological issues,
and agency theory as it relates to retail privacy. The
paper continues with a methodology to address the
overall privacy issues of RFID through the applica-
tion of category and solution frameworks. The cat-
egory framework is based on privacy classes of
DeGeorge (2003). The solution framework pro-
posed is based on philosophical foundations, litera-
ture review, and the Fair Information Practices of
the Federal Trade Commission (1998, 2000). These
practices have previously been recommended for
online privacy and electronic commerce. Through
this process, a proposal to address RFID issues is
recommended.
Background of RFID
RFID Technology
RFID has been heralded as a major new technology
that will revolutionize supply chain management.
According to AIM, The Association for Automatic
Identification and Data Capture Technologies, the
use of RFID automates the process of collecting
product and transaction data (AIM, Inc., 2003c). The
actual concept uses three separate components – an
antenna, an RFID tag (programmed transponder with
unique information), and a transceiver (a r.

RFID is a tracking device mostly used in retail products and in some countries it is also used at toll gates. This presentation tells you some basics, history of emergence of RFID and its uses.
Rfid privacy1.1
Radio Frequency Identification (RFID) tags are poised to dramatically increase their presence in business and consumer applications. While offering advantages, this also creates new privacy risks. The document discusses key privacy issues with RFID technology, including tags becoming more unobtrusive and unique identifiers allowing individual object tracking. It recommends responsible development and deployment of RFID to enable benefits while mitigating privacy risks. Microsoft will apply privacy principles to its RFID software tools and applications to respect customer privacy.
RFID Privacy & Security Issues
This document summarizes the privacy and security issues surrounding RFID implementations. It begins with an overview of RFID technology, including its history and how it works. It then discusses several current uses of RFID, such as in toll booths, financial transactions, supply chain management, and healthcare. Potential privacy issues with RFID include tracking individuals via implanted or external RFID tags. Security issues involve cloning RFID tags. The document analyzes these issues through two case studies: issues with the Mifare Classic RFID system and privacy/security vulnerabilities in US/Australian ePassports that use RFID.
Radio Frequency Identification (RFID)
RFID (Radio Frequency Identification) is a technology that uses radio waves to automatically identify objects. It consists of three main parts: RFID tags attached to objects, RFID readers that can read the tags, and a data system to process the information. RFID provides several benefits over barcodes such as not requiring line of sight and being able to identify multiple objects rapidly and simultaneously. However, RFID also faces issues such as higher costs compared to barcodes, lack of global standards, and potential privacy and security concerns. Overall, RFID is a useful automatic identification technology but still has challenges to address before it can completely replace barcodes.
