Essay on 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.

RFID is not new innovation by any stretch of the imagination. It has been around for a considerable length of time. It was utilized at first for vicinity access control. From there on, it developed to be utilized as a part of inventory network following, toll boundary control, and notwithstanding ensuring cars(Potter, 2005).They are different5 types of tags are available.

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

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)

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

RFID is short for Radio Frequency IDentification. The solution is comprised of RFID tags and a device that can read

RFID tags can be either passive, active or battery-assisted passive. An active tag has an embedded battery acting as local power source and periodically transmits its ID signal to the receiver. A

A RFID tag is dynamic or aloof in light of its source.RFID having an installed battery is said to be dynamic and other with no battery is detached. It can be a read just or read/compose which can be changed by any framework client. Read just labels are for the most part utilized as key to a database or some other source.

Passive RFID tags do not have an internal battery so they acquire power through the transmission of energy from radio frequencies that emit from a reader. Hence, in order to receive the power these tags have to be in the range of the reader and require very high signal strength. These can also recognize hundreds of tags at a time if they are in the range of 3-5 meters from the reader. These tags have an ability to read and write the data by storing up to 128kb of data (What is Auto-ID, 2013).

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.

There are two major hardware components that help RFID to work: Tag and Reader. The two devices have an asymmetric relationship in that the tag is simple and offers few facilities besides holding and transmitting the code, while the reader takes the leading role at the cost of higher complexity. RFID tags store information about the item they are attached to. Information generally pertains to identification information; supply-chain information such as attributes, source, destination, and route; and possibly other special parameters. In business model, RFID tags provide the capability for seamless and continuous two ways communication as an object moves through a supply chain. This means that any object bearing a tag can become networked without human intervention or manipulation by automated machines, as is the case with bar codes. Most of the time, the tag is placed on

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.

The advantages associated with using RFID technology for supply management are clearly the reason why Harley Davidson would even consider implementing its use. According to the text, RFIDs can be read much more quickly and with a higher degree of accuracy than bar codes. Bar codes must be

Communication of data between tags and a reader is by wireless communication. Two methods distinguish and categories RFID systems, one based upon close proximity electromagnetic or inductive coupling and one based upon propagating
