How Rfid Technology Works And Talk About Its History

RFID has been around longer than the average American realizes. In World War II we start to see this new technology emerge in the form of a radar. A handful of nations used the radar to detect approaching planes from miles out. While this was handy, the problem with the radar

The advent of RFID technology represents a stark dichotomy in its potential impact to retailers and consumers. For retailers, it is a boon because it allows for efficient product tracking and allows for very finely targeted marketing to consumers based on what they buy or even just what is in their cart. For consumers, many of the benefits for the retailer lead to an easier and efficient shopping process but there are enormous implications related to privacy and how far retailers can really go with the technology.

Radio Frequency Identification (RFID) transmits stored information between a reader and a tag, over low frequency electromagnetic radiation, the transmitted information can then be used for a variety of purposes, which make it essential to modern society, including uses in: identification, security, payment, and tracking. While RFID has a significant number of uses, there are a number of ethical issues which must be tackled.

RFID (radio frequency identification) is an new technology that threatens to take the place of bar codes in the supply chain world. The technology uses electromagnetic fields to automatically identify and track tags attached to objects. This innovation can provide many benefits in logistics and may revolutionize the entire industry. But, even though the technology provides many benefits, it also has many drawbacks and may not yet be developed enough to become the industry standard. The technology also may not be beneficial or cost effective for every business and will require a total overhaul of a businesses infrastructure, which can be extremely costly. Furthermore, both bar codes and RFID technology have many pros and cons, also industry may not be ready to implement RFID into their infrastructure.

Radio Frequency Identification (RFID) technology has a long-standing history despite its more recent application in society and infrastructure. The understanding of electromagnetic energy in the early 1800s followed by the discovery that light and radio waves are a form of electromagnetic energy by Michael Faraday in 1846 began the process to RFID technology. The advances led to German physicist Heinrich Rudolf Hertz being the first to transmit and receive radio waves in 1887. (Landt, History of RFID, p. 7).

RFID (radio frequency identification) uses radio waves to transmit information between RFID tags (chips) and RFID readers (What is RFID?, n.d.). There are two basic types of RFID tags. Active tags are larger and more expensive because they require an independent power supply to function, passive tags are cheaper, smaller and do not need a separate power supply (The Different Types of RFID Systems, n.d.). Initially, we will be implementing the use of passive RFID tags, which will help control the costs of this project. Once the RFID project is functioning according to our expectations, we will expand our RFID system to include the use of active RFID tags. The implementation of RFID technology will require a significant financial investment for a system-wide implementation. Depending upon the extent of our investment in RFID technology, we could enhance our control of access to certain areas, improve inventory management, and monitor our patients ' movements throughout our RFID-equipped facilities (Niles, 2015, p. 384)

In a typical RFID system, individual objects are equipped with a small, inexpensive tag which contains a transponder with a digital memory chip that is given a unique electronic product code. The interrogator, an antenna packaged with a transceiver and decoder, emits a signal activating the RFID tag so it can read and write data to it. When an RFID tag passes through the electromagnetic zone, it

A RFID tag is a “Radio Frequency Identification Tag” is a device that is used as a specific identifier of the object it is attached to. It signals can be read when within proximity of a device built to read its radio waves. They are small chips that are built from silicon and are usually used for products in stores, ID cards, and even cars (Abelson, Ledeen, Lewis 25).

This is not a foreign concept, but it can now be optimized. With RFID you can track item levels through all levels of process. Being able to track items even into the retail environment could give manufacturers the edge they need when trying to find buying trends and demographic marketing tactics.

A RFID system has tags, or labels affixed to the objects which to be identified, it works as two-way radio transmitter-receivers called interrogators or readers send a signal to the tag and read its response.

“RFID (Radio Frequency Identification) can be defined as an automatic identification technology which uses radio-frequency electromagnetic fields to identify objects carrying tags when they come close to a reader.” [2]

There are two major hardware components that help RFID to work: Tag and Reader. The two devices have an asymmetric relationship in that the tag is simple and offers few facilities besides holding and transmitting the code, while the reader takes the leading role at the cost of higher complexity. RFID tags store information about the item they are attached to. Information generally pertains to identification information; supply-chain information such as attributes, source, destination, and route; and possibly other special parameters. In business model, RFID tags provide the capability for seamless and continuous two ways communication as an object moves through a supply chain. This means that any object bearing a tag can become networked without human intervention or manipulation by automated machines, as is the case with bar codes. Most of the time, the tag is placed on

RFID is an emerging technology with a wide spectrum of application. Since the emergence of RFID, the technology is still in the testing stage and is used mostly in supply chains but is now making its way to everyday life. RFID tags can now be implemented in personal possession or even implanted in people, it is possible to read personal information of people without their permission and this raises a serious security and integrity concerns. This report broadly examines the present and ongoing research methods used to protect the privacy and

RFID technology is not only used at gas stations, restaurants, and department but also at

RFID or radio frequency identification is the name given to the "technology that uses radio waves to transmit data and uniquely identify an animal, person, or thing" ("radio-frequency identification," 2013). An RFID system includes a transponder including an antenna and a chip that can easily store a significant amount of data such as location details, manufacturer details and product numbers if any. There are three basic types of the RFID readers. Fixed readers with an external antenna which are often used at the entry points of the yards. Handheld readers are used by personnel moving through the yards or the space. Then there are mobile readers which are set on the moving vehicles and moving equipment for increasing accuracy and tracking the process ("Advantages of RFID in Transportation and Logistics", 2011).
