Due to the Wal-mart initiatives there has been a wide uproar in the industry about RFID. As a result of this mad rush people are implementing RFID systems without truly understanding the benefits and negatives of the implementation. The industry tends to think that RFID is a solution to every enterprise problem today! That is clearly not true. RFID is not a solution; instead it is merely an enabling technology and needs to be understood clearly to get the maximum benefit. This paper aims at clearly defining the potential of RFID by clearing the myths and by laying out a procedure for entrepreneurs to implement their RFID systems.
Before we go deeper into the implementation, it is first important to understand what RFID is? The next section gives a brief description of the technology itself.
RFID technology is based on the simple idea that an electronic circuit or tag, self powered (using a battery) or powered intermittently through radiation from a distance, can transmit information in air that can be read by a reader located at a distance. These tags are nothing but plain antennae bonded to a silicon chip kept inside a plastic or glass case. Tags operate differently depending on the frequency of operation.
The various radio frequencies that are being used by Wireless systems are illustrated in Figure. 1. There are four dominant bands in which most modern day communication occurs. The first is the Low Frequency (LF) band which spans the area around 100KHz. It is followed by the High Frequency (HF) band in the 10 MHz area. The other frequencies are the Ultra High Frequency (UHF) and the Microwave that are in the 900MHz and the 2GHz area respectively. UHF is used worldwide for cellular phones, while microwaves are used for Wifi, Bluetooth, and other recent broadband data communication systems.
