Pros and Cons of RFID Tech­nol­ogy

Electronics For You - - SENSORS -


1. RFID tags are rugged and ro­bust and can work in harsh tem­per­a­tures and en­vi­ron­ment. The RFID sys­tem works at a re­mark­ably high speed, even in ad­verse con­di­tions. 2. RFID tags are avail­able in dif­fer­ent shapes, sizes, types and ma­te­ri­als. The in­for­ma­tion on the read-only tag can­not be al­tered or du­pli­cated. Read-write tags can be used re­peat­edly. The RFID tags are al­ways read with­out any er­ror. Di­rect phys­i­cal contact be­tween the tags and the reader is not re­quired. RF tech­nol­ogy is used for com­mu­ni­ca­tion. Mul­ti­ple RFID tags can be read at the same time. The RFID tags can be read in a bulk of ten to 100 tags at a time. Read­ing of the tags is au­to­matic and in­volves no labour. 5. RFID sys­tems can iden­tify and track unique items, un­like the bar code sys­tem which iden­ti­fies only the man­u­fac­turer and the prod­uct type. 6. The en­tire RFID sys­tem is very re­li­able, which al­lows the use of

RFID tags for se­cu­rity pur­pose. 7. The stor­age ca­pac­ity of the RFID tags is greater than of any other

au­to­matic iden­ti­fi­ca­tion and track­ing sys­tem.
