Annotated Bibliography On Security System Using Rfid Technology

track the target once it is attached on an RFID tag. Passive tags are used to attach on the target object because they are much cheaper, long lived, lightweight and have a smaller foot print. The reader can communicated with host computer through RS232.

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.

Radio Frequency Identification – RFID – is an established data-carrying technology used throughout industry. Data relating to an item is stored on a tag, which is attached to the item. The tag is activated by radio waves emitted from a reader. Once activated, the tag sends data stored in its memory relating to the item back to the reader. This data can then be shared between organizations and trading partners via the EPCglobal Network in a secure manner.

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)

Over the years Radio Frequency Identification (RFID) has started to become an important factor in not only healthcare but banking, identification, and many more. RFID for the most part has been implemented in the day to day functions in healthcare. The aim of RFID in healthcare is to lower cost and time of common task, all while being able to efficiently manage staff, patients, and inventory in the hospital. In regards to real time location and authentication systems, RFID can use this to track patients, documents, equipment and/or wait room activity. From the security aspect, RFID can be used to control access to equipment and certain locations inside of a hospital. This paper will discuss those functions, as well as how

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 passive RFID tag, more commonly used, is one that is not connected to a power source. These tags rely on the electromagnetic field that is generated by specific RFID tag readers to create enough electrical charge to transmit the stored data in radio waves (Venkateswara, 2011).

The RFID distinguishing proof tag is a transponder. A transponder is characterized as a device that transmits its very own signal when it gets a signal from an outside source.

The use of a microphone and speaker coil was the first example of using backscatter radio link to carry substantial amount of information. This was done in 1948. The passive back scatter radio technique was used when the radar or reader is very far away from the object to be identified. But if the object to be identified is very close to the reader i.e. in the range of few centimeters then there is no need for passive back scatter technique. In this case we used a technique in which the receiver and the transmitter are inductively coupled. Such systems can operate at very low frequencies i.e. few kilohertz to few megahertz. These are also called as low range transmitters and receivers because they operate in a very low range of centimeters. Talking about the manufacturing of such cheap transponders these can be made by using a sensitive magnetic strip. When the reader comes close to the strip it vibrates and takes the necessary information. They were developed in 1960’s wildly used in retail stores and etc. Now if we want more ID space we have to slightly change the circuitry of the transponder. Such circuitry can be composed with the help of a capacitor and the inductor which operates at a resonant frequency. Such a system will provide much larger ID space than the previous ones. Then inventors thought of a more sophisticated tag in which radio frequency can also be used as a power source for the tag. Such a tag can be made by

RFID technology became known because of its use in World War II aviation technology. The British Royal Air Force used early RFID during the war in its Identify Friend or Foe systems (IFF) to distinguish allied aircraft from unknown aircraft. The military continues to use more advanced forms of IFF technology today. But early patents in radio transmission for automatic object detection preceded early RFID technology – including the Radio Detection and Ranging system (RADAR) by Robert Watson-Watt in 1935. (Weis RFID) The key difference between RADAR and RFID is the ability to determine what is being detected, not just that it is present. The Germans developed the first known passive RFID system by simply rolling their planes while returning to base to change the signal received using RADAR (RFID Journal). Because RFID functions similarly to RADAR “it is not unexpected that the convergence of these two radio disciplines and

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).

RFID refers to any system that can transmit identification numbers over radio. RFID system is made up of a unique identification number, which is allocated to a specific item, an identity tag which is attached to the item with a chip capable of storing a unique identification number, networked RFID readers and data processing systems that are capable of collecting signals from multiple tags at high speeds and of pre-processing this data, and one or more networked databases that store the product information RFID is a wireless technology, which allows transmission of information without the physical connection. In its most basic form, an RFID system has two components: tags and readers. A tag (transponder) consists of a microchip that stores identification data of the item to which it is attached and an antenna to transmit this data via radio waves. A reader (interrogator) sends out a radio signal and prompts the tag to broadcast the data contained on its chip. The reader then converts the radio waves returned from the tag into digital data and forwards them to a computer system. A reader can scan an area for any tags that are tuned to the same frequency as the reader. The frequency on which the RFID system operates designates the intensity of the radio waves used to transmit information and is a key factor in determining performance levels and applications for the system. Nearly all RFID systems operate

Radiofrequency identifies the subject by reading the tags attached to the subject. These tags contain electronically stored information which is captured by the reader. Tags may either be powered by electromagnetic induction, some may collect energy from the interrogating radio waves and act as passive transponder and some are powered by batteries and can operate at hundreds of

Radio Frequency Identification (RFID) is a framework that uses radio recurrence to transmit identification wirelessly. Its functionality is much more powerful than bar code system, with which a contacting reader must be used to read the standardized tag. The Food and Drug Administration (FDA) of the United States announced in 2004 to embrace RFID innovation for the identification of fake

A RFID comprise of a label/mark connected to an item. Two-way radio transmitter-collectors called cross examiners or perusers send a sign to the label and read its reaction.
