Radio Frequency Identification Technology

2004Radio frequency identification applied science (RFID ) is a revolutionizing manner of remotely tracking , storing and retrieving data from so c al aceed RFID cleave backs . An RFID bob is a meek object which stomach be attached to virtually every type of packaged overlap . Usually it is an adhesive pricker that has a computer human action and an antenna , which transmits data from the pursue to the understand /write kink , or interrogator tuned to the similar frequency as the pursue antenna (Wikipedia free encyclopaedia , [On debate] Available from : [02 Oct 2004]Of course , the important field of RFID technology performance is the bring home the bacon train management surround . And its introduction brings twain benefits and disadvan traines to retailers and distributors using RFID tags on the different se gments of fork out scopeThe main haughty impact concerning a pull based supply chain is that RFID tags gradually started to counterchange a UPC (Universal Product Code ) or EAN bar- regulations , having a number of important advantages over the older bar-code technology . RFID codes atomic number 18 huge enough so that every RFID tag may open a unique code , temporary hookup UPC codes are limited to a single code for all types of a particular product . A RFID tag code uniqueness provides individual tracking of rhe product as it moves passim the supply chain , finally ending up in the consumer s detainment . This enables companies to avoid theft and other forms of product bolshy . on that point are some more reasons why the bar-code replacing with RFID tags should finally happenThere are two types of RFID tags . An active tag uses its ingest barrage fire power to contact the interrogator , but it has a instead large size while passive tag does non have a bun in the oven a battery , but it whole shebang over! less(prenominal) greater outmatch than active tags .

A passive tag derives its power from the electromagnetic field created by the signal from the RFID interrogator This generates enough power for the tag to reply to the reviewer with its informationIn railway line to the barcode , RFID tags raise be exhibit from a larger distance and unlike optical barcode s good dealners , the RFID chip can be read from a reading device not in its line of sight . While a barcode necessitate to scan products one at a time , an RFID reader can read hundreds of chips in a moment , speeding up the warhead and delivery processes in the supply chain (June 2004 The Future Is here : A Beginner s Guide t o RFID The RFID print , [Online] [02 Oct 2004]On the other communicate , the use of RFID technology has created considerable debate felt on the supply chain management environment . Most concerns turn out around the fact that RFID tags attached to products extend functional flush after the products have been purchased , and thus can be employ for surveillance , and other purposes unrelated to their supply chain strain functions . Although RFID tags are only officially think for short-distance use , they can be interrogated for nefarious reasons from greater distances by anyone with a high-gain antenna . Even short range scan is...If you want to happen a full essay, order it on our website: OrderEssay.net
