Radio Frequency Identification Technology

2004Radio frequency identification applied science (RFID ) is a revolutionizing method of remotely tracking , storing and retrieving data from so c aloneed RFID hang backs . An RFID bob is a meek object which stomach be attached to virtually every type of packaged product . Usually it is an adhesive pricker that has a computer chip and an antenna , which transmits data from the pursue to the read /write device , or interrogator tuned to the similar frequency as the tag antenna (Wikipedia free encyclopaedia , [Online] Available from : [02 Oct 2004]Of course , the main field of RFID technology performance is the bring home the bacon string management surround . And its introduction brings twain benefits and disadvantages to retailers and distributors using RFID tags on the different segments of supply scopeThe main haughty impact concerning a pull based supply chain is that RFID tags gradually started to replace a UPC (Universal Product Code ) or EAN bar- regulations , having a number of important advantages over the older bar-code technology . RFID codes are long enough so that every RFID tag may have 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 hands . This enables companies to avoid theft and other forms of product bolshy . There are some more reasons why the bar-code replacing with RFID tags should eventually happenThere are two types of RFID tags . An active tag uses its ingest battery power to contact the interrogator , but it has a quite large size while passive tag does non require a battery , but it whole shebang over less greater distance 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 contrast to the barcode , RFID tags raise be read from a larger distance and unlike optical barcode scanners , 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 loading and delivery processes in the supply chain (June 2004 The Future Is Here : A Beginner s Guide to RFID The RFID print , [Online] [02 Oct 2004]On the other hand , the use of RFID technology has created considerable debate felt on the supply chain management environment . Most concerns revolve around the fact that RFID tags attached to products extend functional even after the products have been purchased , and thus can be used for surveillance , and other purposes unrelated to their supply chain inventory 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 get a full essay, order it on our website: Ordercustompaper.com
