Rfid And Its Impact On Global Supply Chain Management

As RFID technology evolves and becomes less expensive, there will be an increase in the number of companies and vendors using the technology. Eventually, new applications will be developed and these systems may even be able to solve common or unique problems associated with business in today’s market.

In 1939, the British Royal Air Force developed an “identify friend or foe” transponder that could interpret received radar signals to distinguish friendly aircraft. This was the first example of a device that could automatically and remotely identify itself to another device. RFID worked on the same basic principle: A signal was sent to a transponder which either reflected back a signal (passive system) or broadcast a signal (active system). Research and development in radar and radio-frequency communication systems continued through the 1950s and 1960s. In 1973, an American entrepreneur was awarded a patent for a passive transponder used to unlock a door without a key. When a card with an embedded transponder communicated a signal to a reader near the door, the reader detected a valid identity number stored within the RFID tag and unlocked the door. A similar idea, an automated toll payment system, was commercialized in the mid-1980s. By 2005, the use of RFID had expanded. Many companies used RFID tags in employee badges. Several prisons in the United States used RFID tags to track prisoners. In 2004, Boston Marathon participants’ shoe laces contained RFID tags to track and accurately time the runners and to share their progress with spectators. The American Express Blue credit card started including a feature called ExpressPay that

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).

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).

2) That where languages or words or quotation from others papers such as articles, books and journals is used, such have been indicated by quotation marks and appropriate credits have been given to acknowledge the works of such writers or authors.

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

Currently, RFID is being used to incorporate tags in doors and boilers. This is mostly used in many housing associations and for asset management while managing facilities. In UK RFID is being used to track logistics, control quality, reduce waste and asset management. Since, RFID is becoming cheaper, there lies umpteen opportunity for its usage in construction management.

When all is said in done, RFID (Radio Frequency Identification) is a strategy for perceiving a human or item using a radio frequency transmission. The technology can be used to perceive, track, sort or recognize a wide variety of articles. RFID (Radio Frequency Identification) can be portrayed as takes after Automatic ID technology which uses radio-frequency electromagnetic fields to recognize items

Radio Frequency Identification, commonly known as RFID, is a data collection technology that utilizes electronic tags to store data. The tag has many different names such as electronic label, transponder, or code plate. The RIFD chip is attached to an antenna transmitted in kilohertz, megahertz, and gigahertz range. These RIFD tags are similar to barcodes and are used to track items (RFID, n.d.).

In 1960s, RFID began to advance which led companies to use the technology for anti-theft purposes. Electronic article surveillance tags uses radio waves to find out whether a customer had paid for the item. When someone tries to walk out with an item that wasn’t paid for, it gets detected by the reader at the door resulting an alarm. In 1973, the first US patent was issued for an active RFID tag. A RFID tag is saved with a unique numbers which gets broadcasted by a card with the transponder. Therefore, the door would unlock when the reader detects the unique number from the RFID tag. This technology was licensed to different companies, mainly door lock makers. The US government started using RFID to track nuclear materials in the 1970s. The department of Agriculture expands the passive RFID technology to mark cows. The cows were fed with various kinds of medicines and hormones and it is so hard to track how many doses each cow received. A passive RFID solved the problem of cows not getting overdosed through the use UHF radio waves. After, smaller transponders were created that could be injected under a cow’s skin. They still use this technology in cows now days. These low frequency transponder is also used in readers for building access. Later, the commercializing of high frequency enabled companies to have faster data transfer and more range. “Today, 13.56 MHz RFID systems are used for access control, payment systems (Mobile Speedpass) and

Today we are in the era of globalization. In order to expand business one needs to spread their business across territories. So in order to expand and compete with local business or competitors pricing of the product becomes very critical. But expanding business comes with added costs which are due to supply chain and logistics costs which in turn either reduce the profit in a competitive market or by increasing the price companies lose their competitive edge. Hence it is very important for any business to keep a close watch on this cost. One way of controlling the added cost is by effective supply chain, logistics and inventory management.

Airbus has communicated to its suppliers to tag all traceable items with passive RFID transporters (Roberti M., 2015). Boeing is also using this technology to optimize maintenance activities with specific information regarding maintenance history, parts pedigree, etc. (Lu et al., 2006). It means that the most of the parts supplied by these two aircraft manufacturers are already tagged with RFID technology. American airlines can use their business partners experience with RFID technology to improve their warehousing efficiency. Before initiating the RFID project American airlines should discuss and document the different aspects of project including software, hardware, RFID tags, environmental factors, regulatory concerns, reliability, security issues, network, throughput and maintenance.

The history of RFID can be traced back to the times of World War-II. However, the first practical application of this technology could be found in USA where Mario W. Cardullo received the first patent for an active RFID tag with rewritable memory on 23rd January, 1973.

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

Moreover, RFID tags store more dynamic information that is able to edit at every step in the supply chain. The small size of tags and invisible information guarantee security of identification. In addition, a RFID reader can process multiple tags at same time. However, its drawbacks are also not negligible. The most significant issue is the price of RFID systems. Thus, the relative expensive cost of RFID system limits its universality and makes it hard to be widespread utilization. Therefore, with the growth of technology, the chipless RFID is developed to decrease the cost and simplify the fabrication.
