Radio Frequency Identification ( Rfid )

In its basic form, a typical RFID system has two major components, a reader and tags, as shown in Figure 3.1. These tags are made from a tiny chip, also called an integrated circuit (IC), that is connected to an antenna that can be built into many different kinds of tags including apparel hang tags, labels, and security tags, as well as a wide variety of industrial asset tags. The tag chip contains the product's electronic product code (EPC) and other variable information so that it can be read and tracked by RFID readers anywhere(Impinj 2015).

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.

The RFID is considered a significant improvement over the conventional barcode, which needs to be read by scanners in "line-of-sight" fashion and can be stripped away if the paper product labels get ripped or damaged. RFID can also facilitate inter-organizational E-commerce initiatives such as continuous replenishment or vendor-managed inventories (Smaros and Holmstrom, 2000).

While the Radio Frequency Identification Device has been in existence for almost 50 years, the use of this chip in human beings is an advancement of the technology. The chip has mainly been used for tracking animals and goods throughout is existence. Generally, the RFID chip consists of two main parts i.e. an antenna and integrated circuit chip. It's been used as an effective detection mechanism since the antenna can recognize the chip regardless of whether it's within its line of sight (Alam, 2011).

Today, RFID is used in retail, manufacturing, healthcare, agriculture, travel, entertainment, etc. RFID increases efficiency of operations, decreases reliance on manual process, improves asset visibility and traceability, reduces operation costs, and provides useful data for business analytics. There are many different reasons why companies and firms are beginning to make the switch to RFID, some examples are: automating inventory and asset-tracking in healthcare, manufacturing, retail, and business sectors; identifying the source of products, enabling intelligent recall of defective or dangerous items; prevent use of counterfeit products in the supply chain; improve shopping experience for consumers; provide visibility into the supply chain

Technology is quickly evolving and changing our everyday tasks. The next big thing is RFID technology. RFID, also known as Radio Frequency Identification Device, is making it easier for the consumer to pay without swiping their card or without signing. Many already know RFID as pay-pass where you simply wave your credit card over an RFID transmitter to pay for purchases. There are many benefits and cons to this new technology for the consumer and the producer alike.

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 (radio frequency identification) is an new technology that threatens to take the place of bar codes in the supply chain world. The technology uses electromagnetic fields to automatically identify and track tags attached to objects. This innovation can provide many benefits in logistics and may revolutionize the entire industry. But, even though the technology provides many benefits, it also has many drawbacks and may not yet be developed enough to become the industry standard. The technology also may not be beneficial or cost effective for every business and will require a total overhaul of a businesses infrastructure, which can be extremely costly. Furthermore, both bar codes and RFID technology have many pros and cons, also industry may not be ready to implement RFID into their infrastructure.

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

Nowadays, RFID has been used widely in many industrial services, distribution, manufacturing and security. It can help to identify and monitor items (products, people, animals, etc...) wirelessly within a specified range. Although RFID technology dates back to WWII, it has not been used commercially until fairly recently, when Wal-Mart began using it for inventory management. In an attempt to fully integrate the RFID system, thereby substantially saving on logistics and manpower costs, streamlining in-store automatic product management procedure, and raising the company overall operating efficiency Wal-Mart demanded that its top 100 suppliers to affix a RFID tag onto the packaging of the goods they supplied. In an effort to improve business and service quality, save time and effort.

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

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

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

Radio-frequency identification (RFID) is the remote utilization of electromagnetic fields to exchange information, for the reasons of consequently recognizing and following labels joined to protests. The labels contain electronically put away data. RFID utilizes Radio frequency to distinguish and track "labeled" things. This information is then gathered and transmitted to a host framework utilizing a RF Reader. The data transmitted by the tag may provide identification or location information, or specifics about the product tagged, such as price, color, date of purchase, etc.

To deal with problems posed by supply chain issues, exceptional technologies are needed. One such technology is RFID which is an acronym of Radio Frequency Identification. RFID technology is a means of gathering data about a certain item and doesn’t need to see or touch the data reader. It uses the inductive coupling or electromagnetic waves. This technology has unlimited possibilities for connected devices around us right from goods, animals, gates, containers, machines even human are tagged through RFID’s. (ILIE-ZUDOR, 2006)
