Rfid Essay

In its basic form, a typical RFID system has two major components, a reader and tags, as shown in Figure 3.1. These tags are made from a tiny chip, also called an integrated circuit (IC), that is connected to an antenna that can be built into many different kinds of tags including apparel hang tags, labels, and security tags, as well as a wide variety of industrial asset tags. The tag chip contains the product's electronic product code (EPC) and other variable information so that it can be read and tracked by RFID readers anywhere(Impinj 2015).

The RFID system mainly includes three parts: reader, antenna, and RFID tag, as shown. Because of the uniqueness of the RFID tag, the reader can locate and

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).

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 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.

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

As technology advances so does the threat to our privacy as citizens, we enter into this technological world worried only with what’s new and hot and not diving deeper into how these devices are collecting data on us. One of these new devices is called a Radio Frequency Identification (RFID) it’s a wireless system of both what is called tags and readers that pick up radio waves and hold information. The many uses include Inventory control, Equipment tracking, Out-of-bed detection and fall detection (FDA).

Measures: In this paper, Kelly and Erickson discuss RFID technology and its many benefits as well as the privacy concerns for RFID technology. Kelly and Erickson also go over numerous comparative studies on RFID technology.

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, or Radio Frequency Identification, is becoming the new technology through which data can automatically be collected and transferred, along with the capability of tracking assets such as inventory, machinery, or even people. RFID readers collect, store, and relay important data to other application systems, and receives this information from RFID tags. The two types of RFID tags are active and passive. Active RFIDs use power and can broadcast signals to the RFID readers, while passive RFIDs are powerless and only communicate with the reader when within a specified distance. Passive RFID’s are typically used to identify things, whether it be patients at a hospital, drug authentication, inventory, etc; they are very similar to barcodes.

The necessary communication between tags and readers occurs by the radio frequency communication. This communication gives the RFID powerful capabilities, but it also leaves the door open to several key threats like unauthorized access to tags and side channel attacks.

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.

Though RFID has it’s benefits there are too issues that arise with this form of technology. Reader collision and tag collision may occur if there is an overlapping of readers and signals have a transmittal interference with one another. This causes a inability for a specific query to respond towards the direct path within the network. If this happens it could cause a break in the movement of goods from point to point by rerouting that product to a different destination. Tag collision happens normally a small amount of the time due to the fact that its efficiency is highly sophisticated, however, if it does it could serve as costly and prevent future business from happening with loyal customers.

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