Questions On Supply Chain Management

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.

27. Cite three advantages for using an active RFID tag. The power consumption of the G2C501 is 10μA in the sleep mode and uses two AA batteries with an expected lifetime of five years, it works in the standard 915 MHz range, and it also has location capability.

The RFID technology consists of three kinds of tags i.e. active RFID tags, passive RFID tags, and battery

In this day and age we have many ways of communicating with each other, or as some may say, “Tracking down one another.” I can remember when I was younger talking in chat rooms on the computer was so much fun and an awesome form of communication. Now we have letters, vehicles, cell phones, computers, and several other ways to communicate. In this paper the topic is an object known as the Radio-Frequency Identification (RFID) chip implant, which has greatly affected our society. While the common conception before the technological advances was that the chip was not for human use, the research that has been done on the RFID has furthered its uses. Since everyone is entitled to their own opinion, we are going to have patrons who support the RFID chip implant and those who do not which we will look into.

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 RFID market has continued to grow at a steady rate. According to a new RFID sector survey by IDTechEx Research, “The RFID market will reach $23.4 Billion in 2020. This includes tags, readers and software/services for RFID cards, labels, fobs and all other form factors - for both passive and active RFID.” (IDTechEx). RFID is a technology that will continue to play a critical role in a variety of industries as they both grow and develop.

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 is simply a wireless technology used to store information on an integrated circuit which is commonly referred to as a tag. The IoT suggest that we could potential see billions, if not trillions of these device all cross communicating with one another. These inexpensive tags can be placed on objects devices and even people

The Department of Homeland Security defines Radio frequency identification, or RFID, as a ‘technology that uses

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

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).

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

A passive RFID tag, more commonly used, is one that is not connected to a power source. These tags rely on the electromagnetic field that is generated by specific RFID tag readers to create enough electrical charge to transmit the stored data in radio waves (Venkateswara, 2011).

A RFID comprise of a label/mark connected to an item. Two-way radio transmitter-collectors called cross examiners or perusers send a sign to the label and read its reaction.

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.
