RFID Technology Essay

RFID is a general term that is used to severalize a system that transmits the identity selective information of an object wirelessly, using radio set waves. This is sometimes referred to as contact-less technology and a typical RFID system is make up of three components tags, readers and the host computer system. Tags An RFID tag is a minute radio device, its also referred as a transponder. The tag comprises of a simple silicon microchip attached to a small savourless aerial and mounted on a substrate. The whole device merchantman then be encapsulated in different materials (such as plastic) dependent upon its think usage.The finished tag wad be attached to an object, typically an item, corner or pallet and read remotely to ascertain its identity, position or state. Different types of RDIF Tags available ar passive and active, used as per the RDIF info read / write requirement. Readers The reader, sometimes called an interrogator or scanner, sends and receives RF inform ation to and from the tag via antennas. A reader may have multiple antennas that atomic number 18 responsible for sending and receiving radio waves.Host Computer The data acquired by the readers is then passed to a host computer, which may run specialist RFID parcel or middlew be finishing to filter the data and route it to the correct IS application as processed useful information. RFID can help hospitals to locate equipment more quickly, logistics providers to improve the management of moveable assets, brings efficiencies in the bring out chain by tracking goods from the point of manufacture through to the retail stores, used as EZ card for toll-collections, remote car door access.Use of RFID technology can add business productivity and reduce associated costs. Because of such potential benefits of RFID, many an(prenominal) of the worlds major retailers have adopted RFID tagging for pallets and cases shipped into their distribution centers. To understand that companies be nefit from the advantages RFID provides it is important to understand how to adopt this technology. RDIF technology is been accepted by many retail chains like Wal-Mart, Tesco, Metro etc. For the supply chain and operations it provides increased levels of product and asset visibility.Retailers are spirit at using the RFID technology to automatically receive shipments, and have great visibility into the merchandize in the warehouse and on the store shelves. Few of the menses Issues Facing RFID Adoption * Globally interoperable standardization problem RFID has been apply in different ways by different manufacturers global standards are still being worked on. Because no global standards defined for RFID adoption, interoperability between applications or devices are not possible, which can significantly accelerate the adoption of RFID technology. * surroundings Working environment is another bring down of RFID Usage.The first one is weewee and liquids which can absorb the radio e nergy signals and thereby limit shake off or prevent tag read/write operations altogether. Metals are another material that generally reflect radio frequency signals and rid of the radio waves, thus altering their path. The temperature of the tagged products also affected the readings. some other issue in cased by dense reader or dense tag environment are conflict which cause misfortunate read rates. Dense reader environment consist of several readers places in one closed area resulting same tag been read by multiple readers resulting reader collision.A dense tag environment involves tags fixed too closely to each other resulting in tag collision because of overlap in electromagnetic waves generated by the tags interferes when being interrogated by the reader. rightfulness type of tag/reader has to be used depending on the product, tagging level, and in operation(p) environment. The right fit is in many cases obtained through tests, which will increase read rates and accurac y. * Data management Many conversations about RFID needfully end up by high volume of data and data management issues that are expected to arise from tagging individual products especially in retail store environment.Data management is a key issue for any organization deploying RFID technology, and the robust middleware is compulsory to handle that much touchstone of data and route it to the right database is most concerned. The right architecture is required to filter and translate RFID into useful information. Also its important to localise what useful RFID data should be collected and stored, which will enable easier data management and processing.
