RFID

 

What is RFID ?


Radio frequency identification (RFID) technology uses wireless radio communications to uniquely identify objects or people, and is one of the fastest growing automatic data collection (ADC) technologies.


RFID creates an automatic way to collect information about a product, place, time or transaction quickly, easily and without human error. It provides a contactless data link, without need for line of sight, for example articles inside a cardboard box, or concerns about harsh or dirty environments that restrict other auto ID technologies such as bar codes.


In addition, RFID is more than just an ID code, it can be used as a data carrier, with information being written and updated to the tag on the fly.

 

 

 

What does a complete RFID system consist of?


Included in a RFID system are a number of components including tags, handheld or stationary readers, antennas, and system software. A reader comprises of a transmitter, receiver, control module and communication functions, sometimes called a transceiver in radio terms for it to link to a controlling PC.


The transponders or tags are used to identify objects, which can be uniquely programmed with information about the objects. Readers should have an attached antenna, which is used to transmit and receive the radio frequency signal. Each reader is accompanied with PC compatible software that allows the user to read and program tags.
