Radio Frequency Identification ( Rfid ) Essay

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.

While the Radio Frequency Identification Device has been in existence for almost 50 years, the use of this chip in human beings is an advancement of the technology. The chip has mainly been used for tracking animals and goods throughout is existence. Generally, the RFID chip consists of two main parts i.e. an antenna and integrated circuit chip. It's been used as an effective detection mechanism since the antenna can recognize the chip regardless of whether it's within its line of sight (Alam, 2011).

First of all, what are RFID chips, and what are they capable of? In more detail RFID stands for Radio Frequency IDentification, a technology that uses tiny computer chips smaller than a grain of sand to track items at

Radio-Frequency Identification chip implant “is an object that can be attached to or incorporated into a product, animal, or person for the purpose of identification using radio waves” (Smith 123). The implant is a “typical diameter of an injectable micromodule is 2–3 mm, and its length is 1–1.5 cm. The shape is usually cylindrical to facilitate passage through a hypodermic needle” (Troyk 179). This is not the first time the world has heard of the RFID. The device has been around for quite for some

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

RFID tags are an acronym for Radio Frequency IDentification and although can be used and applied for a multitude of purposes in the world, the greater majority of them are used to prevent theft at the supermarket or department store. However, some progress had been made in the field of electronic management, of the most notable being embedded inside a library book’s cover in order to automatically check it out to the patron to injecting the rice-sized tag into a pet or human to identify its location. The benefits of this tag are great though, much more than exploited. The RFID system contains of two primary components: the transmitter and the receiver which operate per the name by the former transmitting radio signals and the latter receiving them. The radio signals used are similar to

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)

Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. The tags have stored electronical information. Generally speaking, there are two types of RFID tags, passive tag and active tag. Passive tags collect energy from a nearby RFID reader 's radio waves. Active tags have a local power pack unit such as a battery and may operate at hundreds of meters away from the RFID reader. RFID technology was first used during in 1940s, in World War II RFID was used to identify aero planes. The goal was to use the aero plane 's radar signal to read an ID number in order to confirm whether they were allies or enemies. As time goes by, RFID technologies are now widely used in almost all industrial sectors, for example aerospace, automotive, logistics, transport, health, life, etc. In our following report, we will discuss the technologies used in RFID, differences between Barcoding and RFID, current bottlenecks of RFID development, and visions of RFID usage in the future.

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.

The name Radio Frequency Identification (RFID) dates back to the early 1990s. The technology has roots in radar-related work done in the 1940s. During World War II, the military used transponders for the important purpose of identifying a returning aircraft as friend or foe. These systems remain in use today. The military continues to invest in new uses of radio and radar technologies that ultimately could provide the scientific foundation for future RFID enhancements. The commercial market took longer to develop. During the 1960s, electronic article surveillance became the first rudimentary application of RFID that was applied in commercial

The Radio Frequency Identification Device (RFID) is a powerful technology for companies in the logistics and supply chain management industry. According to Jakobs (2000), he states that the RFID system use tiny tags with embedded microchips that contains data. This data contains the location and information about the product/item and transfers the data to RFID readers through radio signals.

The components of an RFID system are the tag, the reader and the host computer system, which has the software that works as an interface between the data collected and storage device by converting the same into useful information. RFID has immense potential for all parties in the supply chain, to mention few:

Identifying any object using radio frequency is termed as RFID. The major advantage of RFID over barcodes is that using RFID items can be scanned even if they are not in line of sight and that too without manual support. [4] RFID network consists of three major components: RFID tag or transponder, Antenna or receiver and reader.

Abstract—Radio Frequency Identification (RFID) and Wireless Sensor Networks (WSNs) are two significant wireless technologies. RFID and WSNs are well known both identification and data transmission they are widely used in applications for environmental and health monitoring. Though the integration of RFID and WSNs fascinates little attention from the research community. In this paper, a Hybrid RFID and WSN system (HRW) that cooperatively integrates the traditional RFID and WSN systems for efficient data collection in large-scale mobile monitoring applications. HRW has hybrid smart nodes that combine the function of RFID tags, the minimized function of RFID readers, and wireless sensors. Hence, nodes can read each other’s sensed data in tags, and all data can be rapidly transmitted to an RFID reader through the node that first extends it. The RFID readers transmit the collected data to the back-end servers for data processing and management. The result of the proposed method improves the performance of HRW in terms of the cost of arrangement, transmission suspends, capability and tags capacity requirement.
