Rfid Technology And Its Applications

Regardless of the frequency, method of communication, or the power supply, the goal of any RFID system is to enable specific data to be transmitted between a portable device and the tag, and then be processed and used accordingly. RFID systems are used for objects which get lost, stolen often, underutilized, or difficult to locate in a timely manner.

The RFID is considered a significant improvement over the conventional barcode, which needs to be read by scanners in "line-of-sight" fashion and can be stripped away if the paper product labels get ripped or damaged. RFID can also facilitate inter-organizational E-commerce initiatives such as continuous replenishment or vendor-managed inventories (Smaros and Holmstrom, 2000).

First and foremost the RFID IC or (Radio Frequency Identification Chip) is a tag, label, or card that can exchange data with the reader using its built in antenna and its IC (Integrated circuit ). There are a numerous amount of different things that helps tie this chip tie together, such as your personal ID, Medical history , bank information, and all of the other information government wants to know about you. The chip is inserted by doctors in one of your hands right between your index finger and you thumb they say it take no longer than thirty seconds to a minute.

Today, RFID is used in retail, manufacturing, healthcare, agriculture, travel, entertainment, etc. RFID increases efficiency of operations, decreases reliance on manual process, improves asset visibility and traceability, reduces operation costs, and provides useful data for business analytics. There are many different reasons why companies and firms are beginning to make the switch to RFID, some examples are: automating inventory and asset-tracking in healthcare, manufacturing, retail, and business sectors; identifying the source of products, enabling intelligent recall of defective or dangerous items; prevent use of counterfeit products in the supply chain; improve shopping experience for consumers; provide visibility into the supply chain

In this day and age we have many ways of communicating with each other, or as some may say, “Tracking down one another.” I can remember when I was younger talking in chat rooms on the computer was so much fun and an awesome form of communication. Now we have letters, vehicles, cell phones, computers, and several other ways to communicate. In this paper the topic is an object known as the Radio-Frequency Identification (RFID) chip implant, which has greatly affected our society. While the common conception before the technological advances was that the chip was not for human use, the research that has been done on the RFID has furthered its uses. Since everyone is entitled to their own opinion, we are going to have patrons who support the RFID chip implant and those who do not which we will look into.

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 uses electromagnetic fields to automatically identify and track tags attach to objects. These tags contain electronically stored information. The information can be read by RFID readers and can only be read if they are within the line of sight of the reader. There are two types or RFID tags; passive and active. Passive RFID relies on RF energy transferred from the reader to the tag to power the tag. Active RFID uses an internal power source, such as a battery within the tag to continuously power the tag and its RF communication circuitry. “The information is transfer efficiently and automatically without human intervention.” (Yao, 2012)

Variations of RFID technology have been in use since the 1940 's. RFID is an acronym for radio frequency identification. In application RFID is the use of radio signals to wirelessly track and identify tags that have been placed on an item. RFID is an emerging technology that is helping transportation companies, retailers, and manufacturers decrease handling times of goods and increase efficiencies at factories, warehouses, and store fronts by tracking objects with greater flexibility and less human involvement. RFID technology is unique and more adaptable than other tracking systems because it does not require a direct line of sight between the scanner and the object being identified. RFID systems can also identify more than one object simultaneously. This flexibility and efficiency adds the type of value that is paramount in just in time principles. This paper will describe RFID technology in detail, and discuss its current uses in security and access control, toll roads, and supply chain management.

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).

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, or radio frequency identification, is the new system that is replacing the use of barcodes. RFID tags allow users to more quickly obtain information from the object that the RFID tag

RFID is a term utilized for Radio recurrence Identification. RFID is a creating innovation and have numerous uses throughout our life.

RFID (Radio-Frequency Identification), a technology once limited to tracking cattle, is now tracking consumer products worldwide. Many manufacturers use the tags to track the location of each product they make from the time it 's made until carried out of the retail store. Outside the realm of retail merchandise, RFID tags are tracking vehicles, airline passengers, Alzheimer 's patients and pets. Soon, they may even track the consumer’s preference for chunky or creamy peanut butter. Some opponents of RFID technology are saying this technology is becoming too common in our everyday lives. Most people are not even aware of all ways these tags are integrated into our lives and the ways this technology may affect them. RFID technology is under the main supervisory body of the ISO/IEC. The ISO/ETC is a joint technical committee of the International Standards Organization (ISO) and the International Electro technical Commission (IEC). Its purpose is to develop, maintain and promote standards in the fields of information technology and Information and Communications Technology (RFID Technology, 2012).

(a) Label after entering the magnetic field, receive the radio frequency signal from the reader, with the energy gained by the induced current send product information stored in the chip (Passive Tag) or by the label initiative to send a frequency signal (Active Tag) reader read the information and the decoding, sent to the central information system on data processing. A complete set of RFID system, through the Reader (Reader) and electronic label (TAG), that is called Transponder and application software system of three parts. The working principle is the Reader to launch a specific frequency radio waves of energy to the Transponder, send the internal data to drive Transponder circuit, the Reader will receive interpreting data in a sequence, for application to do the corresponding processing. RFID card reader and electronic tags between the communication and energy sensing approach can be divided into roughly: Two kinds of coupling and backward scattering. The general low frequency RFID mostly uses the first kind,
