RFID Technology Essay Example for Free

RFID engine room EssayRFID is a general term that is used to describe a system that transmits the identity selective information of an object wirelessly, using radio waves. This is sometimes referred to as contact-less technology and a typical RFID system is do up of three components attachs, readers and the phalanx computer system. Tags An RFID tag is a tiny radio device, its in like manner referred as a transponder. The tag comprises of a simple silicon microchip connected to a dwarfish flat aerial and mounted on a substrate. The whole device can then be encapsulated in several(predicate) materials (such as plastic) dependent upon its intended usage.The finished tag can be attached to an object, typically an item, box or pallet and read remotely to ascertain its identity, position or state. divergent types of RDIF Tags available argon passive and active, used as per the RDIF info read / write requirement. Readers The reader, sometimes called an interrogator or scan ner, sends and receives RF information to and from the tag via antennas. A reader may digest double antennas that argon 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 softwargon or middleware application to filter the data and route it to the place IS application as processed useful information. RFID can help hospitals to locate equipment more quickly, logistics providers to improve the solicitude of moveable assets, brings efficiencies in the supply chain by tracking goods from the point of manufacture through to the sell stores, used as EZ card for toll-collections, remote car door access.Use of RFID technology can ontogeny business productivity and reduce associated costs. Because of such potential benefits of RFID, many of the worlds major retailers perk up adopted RFID tagging for pallets and cases shipped into their distribution centers. To ensure that co mpanies benefit 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 change magnitude levels of product and asset visibility.Retailers are looking at using the RFID technology to automatically receive shipments, and have greater visibility into the merchandize in the warehouse and on the store shelves. Few of the current Issues Facing RFID espousal * Globally interoperable standardization problem RFID has been implemented 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. * Environment Working environment is an new(prenominal) content of RFID Usage.The first one is water and liquids which can absorb the radio energy signals and thereby limit frame or prevent tag read/write operations altogether. Metals are another material that by and large reflect radio frequency signals and deflect the radio waves, thus altering their path. The temperature of the tagged products also touched the readings. Another issue in cased by dense reader or dense tag environment are collision which cause poor read rates. Dense reader environment lie 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 placed 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. adjust type of tag/reader has to be used depending on the product, tagging level, and operational environment. The right fit is in many cases obtained through tests, which will increase read rates and accura cy. * Data management Many conversations just about RFID inevitably 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 required to handle that much amount 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. overly its important to identify what useful RFID data should be collected and stored, which will enable easier data management and processing.
