Introduction
History of RFID
How does it work?
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 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
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).
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
Radio Frequency Identification (RFID) is a technology which makes use of radio waves to recognize devices or persons. In RFID machine is used that look through data carried in a wireless object or tag from an interspace without creating any physical interaction or demanding a line of sight. RFID is working by means of a microchip and an antenna. RFID technic is originated in the 1970s. RFID systems have a variation of applications, containing planning and observing the spot of persons and goods. Customers are probable to interrelate thru RFID network in stores that affix a tiny RFID transponder to manufactured goods, just as a laptop or other gadgets. The RFID transponder contains a chip that has data about the goods, and an antenna
RFID which is one of the human microchip technologies was first used during the World War II. The technology played an important role of identifying friends or foes in the battle field. According to Yechuri (2004), the Friend or Foe (IFF) system was made in order to ensure that related fighters and anti-aircraft organizations could differentiate their own returning bombers from aircraft sent by the enemy. After the World War II was over, an engineer by the name Henry Stockman explored the issue where he published a paper entitled Communication by Means of Reflected Power. In this paper, he explored the issue of passive RFID chips and discussed how they were used by military personnel in the war for identification purposes. In the early 1960s, this technology gained recognition and RFID was used to find and access hazardous components and nuclear power (Pollar & Elsen, 2013).
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)
The purpose of an RFID system is to enable data to be transmitted by a portable device, called a tag, which is read by an RFID reader and processed according to the needs of a particular application. The data transmitted by the tag may provide identification or location information, or specifics about the product tagged, such as price, color, date of purchase, etc. The use of RFID in tracking and access applications first appeared during the 1980s. RFID quickly gained attention because of its ability to track moving objects. As the technology is refined, more pervasive - and invasive - uses for RFID tags are in the works.
Introduction: In many industries time is money. When time is money, you have to make sure that you are spending that time in the most effective and efficient manner. With RFID technology you can hit both of these points, making it a “two birds with one stone” scenario. When the systems are implemented properly (and properly is the key point) RFID technology is faster and more accurate than traditional methods of scanning and tracking.
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.
Just as all other technologies have such difficulties, RFID technology has obstacles to overcome. Two main concerns are discussed in this paper: radio wave technology hindrances such as collisions, and the ethical concerns that entangle this controversial yet extremely helpful technology.
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) 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]
Over the years, RFID has gained a high level of popularity and recognition. Due to the diversity of its application, the technology has really drawn the attention of investors especially in manufacturing, transport and logistics, hospital and health care and other commercial industries.
RFID technology is not only used at gas stations, restaurants, and department but also at
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
