Advantages And Disadvantages Of RFID

Advan trailes And Disadvantages Of RFIDThe signifi undersidet advantage of wholly types of RFID systems is the noncontact, non-line-of-sight nature of the technology. Unlike a avoid code, a large publication of RFID tags can be read almost instantaneously by other(a) materials (though some materials may cause problems) and they can be read through plastic, cardboard, wood and etc. Theoretic on the wholey, this means that you could take a p on the wholeet of entangled products, all of which contain individual RFID tags, and have an RFID subscriber read all the tags in spite of appearance the palletized load without having to physically move any of the materials or afford any cases. Thus, catalogue can be performed in a super efficient rule. The RFID tags can store data and can overly be read in challenging circumstances at remarkable speeds, in most cases responding in slight than 100 milliseconds. In inter restless applications much(prenominal) as work-in-process or m aintenance bring in, the read/write capability of an active RFID system is also a significant advantage.RFID equipment damage occurs much less frequently than is the case with magnetic strips or barcodes. RFID tags ar less hypersensitised to damage and can be read through a figure of substances such as ice, snow, paint, fog, crusted grime, and other visually and environmentally challenging conditions, where barcodes or other optically read technologies would be useless. RFID tags can be sealed inwardly a plastic enclosure eliminating many of the problems that encrust bar codes in harsh environments where they be exposed to chemicals, high temperature or moisture, abrasion, dirt and grease buildup, etc. If the implementation provides a significant method to improve business processes, the total cost of ownership should go big money over the years and provide a good Return on investment (ROI). Supply chain management forms the major part of retail business and RFID systems pla y a key role by managing updates of stocks, impartation and logistics of the product. The aim is to inhibit administrative error, labor costs associated with scanning bar codes, native theft, errors in shipping goods and overall take stock levels.The combination of all above mentioned advantages ordain provide quick access to a wealth of information, eliminate human errors, and snip labour which lead to reduce find activity times and to save project costs.5.2 Disadvantage of RFID technology need of standardization, high costs of implementation, technology deployment risks, and the elimination of unskilled labour ar all contributors currently preventing the adoption of new RFID technologies in the construction industry. hail is the biggest hurdle to RFID tags replacing bar codes for item-level tracking of low-cost products. RFID systems be typically more expensive than alternatives such as barcode systems. In addition, software and champion personnel needed to install and operate the RFID reading systems (in a store for example) may be more costly to employ.Liquid and metal surfaces flow to reflect the radio waves, which makes the tags unreadable so, RFID tags cannot be read well when position on metal or liquid objects or when these objects are in the midst of the reader and the tag. The tags have to be placed in confused alignments and angles for victorious proper reading. This is a tedious task when the work involves big firms. scintilla and reader collision are common problems with RFID. Tag collision occurs when many tags are present in a confined area. The RFID tag reader energizes multiple tags simultaneously, all of which reflect their signals back to the reader. This result in tag collision, and the RFID reader fails to antitheticiate between incoming data. RFID reader collision results when the reportage area managed by one RFID reader overlaps with the coverage area of other reader. This causes signal interference and multiple rea ds of the same tag.RFID standards are still creation developed. You dont want to invest in an RFID system that is based on soon-to-be obsolescent specs. RFID technology ultimately involves software that allows each user to be identify by a central database. This infrastructure will certainly be under attack by hackers. Water, static discharge or high-powered magnetic surges (such as lightning strike) may damage the tags.With more research, the flaws and limitations of this technology can be removed. This will make RFID technology very useful for various(a) sectors like retail, and transport. Developments in RFID technology continue to yield larger holding capacities, wider reading ranges, and faster processing. RFID will continue to grow in its effected niches where barcode or other optical technologies are not effective. If some standards grossness is achieved whereby RFID equipment from different manufacturers can be used interchangeably the market will very likely grow e xponentially.6 RFID APPLICATIONSThere are various applications of RFID technology in different industries for both logistical traceability for tracking the localization and progress of an object, and qualitative traceability for associating any additional information to products (Karkkainen, 2005). Retail, food, defence, pharmaceutical, healthcare, manufacturing and transport are just some of the sectors where RFID has already been extensively applied (Wilding and Delgado 2004, ERABUILD Report 2006, and smith and Konsynski 2007). Tagging provides asset visibility, identification and positioning, and enables total inventory management. Different sectors require different approaches but a common factor to all is adequately find out a basic unit or unit set for tagging (e.g. pallets, packages, angiotensin-converting enzyme items, containers, etc.)(Radosavljevic and Dan-Asabe, 2007).Increasingly, retail/CPG and Pharmaceutical companies are looking to use RFID to track goods within t heir provision chain, to work in process and for other applications. Today, CPG and retail companies are using RFID to track promotional displays, reduce out-of-stocks and improve shipping and receiving accuracy. Manufactures are using RFID to track work-in-process, perfect just-in-time manufacturing, improve shipping accuracy, and manage inventory and warrantee information (RFIDJournal, 2010).Auto manufacturers are among the leading users of RFID technology today. or so cars have an RFID reader in the steering column and a transponder in the key. If the ID in the key doesnt match the number the reader is looking for, the car wont stop. This system has greatly reduced auto theft. Auto companies also use RFID to track work-in-process, perfect just-in-time manufacturing, improve shipping accuracy, and manage inventory and warrantee information (RFIDJournal, 2010).Hospitals and health-care providers are using RFID technology to track patients and high-value assets, as well as ensure p atient gum elastic. One company offers a system to track surgical sponges to ensure they are not inadvertently left behind in patients. And many hospitals are now tracking patients to ensure the right patient is given the proper care. These systems tend to reduce the data-entry workload of nurses, and also let them spend more time lovingness for patients and automate the process of billing. Additionally, hospitals are tracking high-value assets, including gurneys, wheel chairs, oxygen pumps and defibrillators. These systems reduce the time employees spend looking for assets, improve asset utilization and sharpen the hospitals ability to performed scheduled maintenance (RFIDJournal, 2010).Pharmaceutical companies are exploring RFIDs potential in many areas, including improving supply-chain efficiencies, complying with government information-collection requirements, reducing counterfeiting creating electronic pedigrees and ensuring public safety by making sure only legitimate drug s enter the supply chain (RFIDJournal, 2010).Thousands of companies around the world use RFID today to improve internal efficiencies. Club Car, a maker of golf carts uses RFID to improve efficiency on its production line (Jonathan Collins, 2004). Paramount Farms one of the worlds largest suppliers of pistachios uses RFID to manage its harvest more efficiently (Bob Violino, 2004). NYK Logistics uses RFID to improve the throughput of containers at its busy Long Beach, Calif., distribution centre of attention (Jennifer Maselli, 2003).http//www.rfidjournal.com/article/purchase/839http//www.rfidjournal.com/article/purchase/810http//www.rfidjournal.com/article/purchase/617http//www.rfidjournal.comWilding, R. and Delgado, T.
