R.F.I.D!!!!!!

What is bar code?According to http://www.inventors.about.com/ , it is method of automatic identification and data collection. The first patent for a bar code type product (US Patent #2,612,994) was issued to inventors Joseph Woodland and Bernard Silver on October 7, 1952. The Woodland and Silver bar code can be described as a "bull's eye" symbol, made up of a series of concentric circles. Well , this is not the subject of the post . The subject is RFID ,Radio Frequency Identification , which is a technology similar in theory to barcode identification but more advanced . According to http://www.webopedia.com/ With RFID, the electromagnetic or electrostatic coupling in the RF portion of the electromagnetic spectrum is used to transmit signals. An RFID system consists of an antenna and a transceiver, which read the radio frequency and transfer the information to a processing device, and a transponder, or tag, which is an integrated circuit containing the RF circuitry and information to be transmitted.

Moreover , RFID systems can be used just about anywhere, from clothing tags to missiles to pet tags to food -- anywhere that a unique identification system is needed. The tag can carry information as simple as a pet owners name and address or the cleaning instruction on a sweater to as complex as instructions on how to assemble a car. Some auto manufacturers use RFID systems to move cars through an assembly line. At each successive stage of production, the RFID tag tells the computers what the next step of automated assembly is.

One of the key differences between RFID and bar code technology is RFID eliminates the need for line-of-sight reading that bar coding depends on. Also, RFID scanning can be done at greater distances than bar code scanning. High frequency RFID systems (850 MHz to 950 MHz and 2.4 GHz to 2.5 GHz) offer transmission ranges of more than 90 feet, although wavelengths in the 2.4 GHz range are absorbed by water (the human body) and therefore has limitations.
RFID is also called dedicated short range communication (DSRC).

The question asked by many people right now is : Can RFID replace Bar code identification ?

In fact I asked this question to two specialists and they had two different answers . The first answer was "because the price of a barcode is so low, it is unlikely that RFID would be a viable replacement". The other specialist disagreed with that , he claimed that RFID is so much more advanced than Bar code . And because of the huge advantage it have money will not be a big problem.

I asked the the same spacialists if RFID code can replace UPS code and they had the same answers as the first time .

I also searched the internet to find out that there are 2 points of view concerning this issue.Some are against the idea of RFID replacing Barcode identification and others are with it .

I know I am not a specialist , but if I was asked my opinion I will be completely with

RFID replacing Barcode . The reason is that we cant refuse a new technology because we dont have money to pay for it . It doesn't make sense!!!!!

In the end , I hope you got information you didn't know before from this post , because this is the main concept of our work .
