Simply, Radio frequency identification (RFID) is a generic term that is used to describe a system that transmits the identity (in the form of a unique serial number) of an object or person wirelessly, using radio waves. It is grouped under the broad category of automatic identification technologies. RFID technology provides a more granular visibility for industrial assets and inventory thereby offering a strategic advantage to the business.
Radio frequency identification (RFID) is a generic term that is used to describe a system that transmits the identity (in the form of a unique serial number) of an object or person wirelessly, using radio waves. It's grouped under the broad category of automatic identification technologies. This system consists of antenna or coil, transceiver with decoder (RFID reader), transponder (RF tag) electronically programmed with unique information.
RF tag is applied to or incorporated into a product, animal, or person for the purpose of identification and tracking using radio waves. Some tags can be read from several meters away and beyond the line of sight of the reader. In addition, RFID is increasingly used with biometric technologies for security.
In this project tags are deployed at different locations in an indoor environment, a RFID reader is interfaced to the Microcontroller (P89v51) to read the location of each tag. The location found is played with a voice chip interfaced to micro controller for assisting blind person.
