RFID System Analysis

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 consist of a tag made up of microchips or a reader with an antenna. The reader sends out some magnetic wave. The tag antenna then receives this waves. Then the RFID tag draws power from the field created by the reader and it use it to power the microchip’s circuit. The chip then modulates the waves back to the reader which converts the waves to a digital data. The cost of a RFID is not quoted because pricing is based on volume.

The wave through which the information is transmitted is referred to as the carrier wave, in RFID the carrier wave is in the radio frequency (electromagnetic radiation with frequencies between 3 kHz – 300 GHz) (Mai, 2017). RFID predominantly uses three radio bands; low frequency (125 – 134 kHz), high frequency (13.56

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 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

The radio frequency identification is the system, which uses the radio wave to read the information the tag. The system consist of three main components RFID tag or transponder, which identify the data carrier in RFID, RFID tag reader or transceiver, which read data from and write to transponder and data processing subsystem, which use the data obtained from the transceiver.

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).

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 systems contribute largely to the wireless revolution that is taking place. RFID or radio frequency identification systems administer powerful technology to transmit data in order to aid in tracking the movement of goods and inventory through a company’s supply chain. RFID systems consist of three main parts which include tags, readers, and a computer system. Ultimately, the tags transmit data to a reader in which captures this data and sends it to a host computer for further processing by an employee of a company, however RFID systems have much more depth to them than just this.

(a) Label after entering the magnetic field, receive the radio frequency signal from the reader, with the energy gained by the induced current send product information stored in the chip (Passive Tag) or by the label initiative to send a frequency signal (Active Tag) reader read the information and the decoding, sent to the central information system on data processing. A complete set of RFID system, through the Reader (Reader) and electronic label (TAG), that is called Transponder and application software system of three parts. The working principle is the Reader to launch a specific frequency radio waves of energy to the Transponder, send the internal data to drive Transponder circuit, the Reader will receive interpreting data in a sequence, for application to do the corresponding processing. RFID card reader and electronic tags between the communication and energy sensing approach can be divided into roughly: Two kinds of coupling and backward scattering. The general low frequency RFID mostly uses the first kind,

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.

Secoundly, a RFID reader, which is a transceiver with a decoder to interpret the data. Whenever the sensor tag is activated on the reader, it will interrogate and decode the data on the

Active tags require the most power because they can initiate communication to other tags or a reader device. They have a greater range of operation and have been applied to asset control and tracking livestock because of the greater range active tags allow (Weis, 2007, p. 10). Therefore, active tags require more maintenance, but they can broaden the scope in how RFID systems can be used. Some active tags can be equipped with an acceleration sensor that can determine when the tag begins accelerating and then transmit a signal to the reader. One example that this can be useful for is in shipping container transportation. Shipping containers can be lost at sea after falling off a ship and traditional RF technology may not be able to detect it in time. However, active tag RFID systems with an acceleration sensor can notify the system when the container begins falling, making it possible to recover (Weis, 2007, p. 10). Figure 3, below, shows the different characteristics of active and passive tags.

Radio Frequency Identification, or as it is more commonly known, RFID, is an automated identification and data collection (AIDC) technology. From access cards to passports to toll tags RFID has now become ubiquitous as an integral part of our daily lives.

RFID tagging is an ID system that uses low-frequency detection device for the purpose of identifying and tracing. It includes the tag, the device which reads and writes and host system for the application of data collection, processing and transmission which relies on storage and retrieve data remotely using a tag or transponder [1].
