What is RFID ?
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 using radio waves.
RFID is designed to enable readers to capture data and transmit it to a computer system—without needing a person to be involved.
A typical RFID tag consists of a microchip attached to a radio antenna mounted on a substrate. The chip can store as much as 240 bits of data.
To retrieve the data stored on an RFID tag, you need a reader. A typical reader is a device that has one or more antennas that emit radio waves and receive signals back from the tag. The reader then passes the information in digital form to a computer system.
Further information on RFID:
An RFID tag is effectively an "intelligent barcode" - the major differences between the two being:
- RFID tags have the ability to carry or access more information about an unique object to which it is attached (item level tagging), whereas barcodes provide generic information about an entire product line.
- RFID tags do not require line of site to be read. Depending on the application and the frequency and antenna design, item-level RFID tags can be read in boxes/crates/cases from considerable distances, through packaging, glass, liquid and in bulk whilst in an RF field, in specific classes or subsets and through opaque cartons, packaging and seamlessly and automatically.
- Barcodes can become damaged and illegible for scanners to read. This is not the case for RFID.
- Barcodes are read only. RFID can bes read / write and can be read at item level.
- RFID tags can be interfaced with computer systems that collect and maintain data
