A Research Study On Radio Frequency Identification

Lately Conner and Martin have been working with “radio frequency identification” (RFID) technology. They have developed a detailed system designed to track inventory items using RFID tags embedded invisibly in products. This technology has numerous inventory

RFID systems are currently being used in manufacturing plants to track parts, stay informed of work in progress, reduce product defects, increase throughput, and manage production of given products. Big name retailers such as Best Buy, Metro, Target, Albertson’s, Hewlett Packard, and Wal-Mart are leading the way in implementing RFID systems. These retailers recognize the need to improve inventory efficiency, ensure products are available to customers as needed, decrease theft, and cut down on costs associated with tracking and processing inventory.

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

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

RFID is a term used for Radio frequency Identification. RFID is a developing technology and have many uses in our life.

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.

RFID or Radio-frequency identification is a technology used to track objects using electromagnetic fields that transfer data. RFID chips are incorporated into small tags, that are then attached to objects that requiring tagging and tracking. As stated by Mark Roberti (2005), RFID has come a long way since being invented in 1935, from being used in the radar system during the world war to being developed into a more passive RFID system by the Germans and then into more advanced roles of anti-theft systems used by many companies in the form of electronic article surveillance tags. This system went on to be used in more advanced uses such as unlocking doors without keys, tracking nuclear materials, automated toll payments, tracking cattle for agricultural use, contactless cards for payment systems and anti-theft systems in cars. Later by 1990s, IBM developed ultra-high frequency RFID system. This system made its way into supply chain management for the purpose of tracking them, thanks to two professors David Brock and Sanjay Sarma who

RFID refers to any system that can transmit identification numbers over radio. RFID system is made up of a unique identification number, which is allocated to a specific item, an identity tag which is attached to the item with a chip capable of storing a unique identification number, networked RFID readers and data processing systems that are capable of collecting signals from multiple tags at high speeds and of pre-processing this data, and one or more networked databases that store the product information RFID is a wireless technology, which allows transmission of information without the physical connection. In its most basic form, an RFID system has two components: tags and readers. A tag (transponder) consists of a microchip that stores identification data of the item to which it is attached and an antenna to transmit this data via radio waves. A reader (interrogator) sends out a radio signal and prompts the tag to broadcast the data contained on its chip. The reader then converts the radio waves returned from the tag into digital data and forwards them to a computer system. A reader can scan an area for any tags that are tuned to the same frequency as the reader. The frequency on which the RFID system operates designates the intensity of the radio waves used to transmit information and is a key factor in determining performance levels and applications for the system. Nearly all RFID systems operate

Imagine a world where all items can be tracked without having to touch or see the item. Thanks to RFID this is now, a reality. RFID technology has been around for decades, but only recently has it gained so much popularity and relevance. In the world of supply chain management, RFID technology can be a game changer that can give firms a competitive advantage.

Harley-Davidson (H-D) and other companies that have many manufacturing plants or production units and various dealerships may consider implementing RFID technology as a means of increasing the efficiency of all parts of its supply chain. An abstract from Columbia Electronic Encyclopedia describes Radio-frequency identification (RFID), as a technology that uses radio waves to transmit data and uniquely identify an animal, person or thing. This case study looks at the potential use of RFID technology to replace bar codes and scanners in Harley-Davidson supply chain. It indentifies some pros and cons of its implementation and addresses the question – What are some of the issues Harley-Davidson will face in

Key difference is bar codes are the traditional id technology and RDIF tags are the new modern technology

Some of the disadvantages of the RFID technology are that it is expensive to install. Small and medium scale enterprises find it costly to use it in their firms and offices. In the case of Harley Davidson, getting products from many different suppliers’ would mean that the tags may have to be installed in liquid and metal products. The problem is that the liquid and metal surfaces tend to reflect the radio waves, which makes the tags unreadable. The tags have to be placed in various alignments and angles for taking proper reading. This is a tedious task when the work involves a large organization like Harley Davidson. Another disadvantage of the technology is that interference has been observed if devices such as forklifts and walkie-talkies are in the vicinity of the distribution centers. The presence of mobile phone towers has been found to interfere with RFID radio waves. Wal-Mart, the retail sector giant, has installed billions of RFID tags in their products throughout the world and they have encountered such problems.

Shopping seems to be a good entertainment. But the huge queue in the supermarkets to scan the products frustrates the customers . Barcode scanning is a time consuming process engaging the customers to stick to the billing section for a long time. Hence there is a need to switch to a Radio Frequency Identification (RFID) system for smart purchase and instant billing .
