What is RFID?
Radio frequency identification, or RFID, is a term for technologies that use radio waves to automatically identify people or objects. It generally has two important components a TAG or a Transponder and a receiver. The tag is basically a has antenna to transmit the waves through an antenna .then the receiver decodes the received information.
How does an RFID system work?
An RFID system consists of a tag made up of a microchip with an antenna, and an interrogator or reader with an antenna. The reader sends out electromagnetic waves. The tag antenna is tuned to receive these waves. A passive RFID tag draws power from the field created by the reader and uses it to power the microchip’s circuits. The chip then modulates the waves that the tag sends back to the reader, which converts the new waves into digital data. This digital data can be passed on to a computer which can use the data.
How much information can an RFID tag store?
It depends on the vendor and the application, but typically a tag carries no more than 2KB of data-enough to store some basic information about the item it is on. Companies are now looking at using a simple “license plate†tag that contains only a 96-bit serial number. The simple tags are cheaper to manufacture and are more useful for applications where the tag will be disposed of with the product packaging.
