What is RFID technology?

RFID Technology has been around for many years now but what exactly is it?

RFID stands for Radio Frequency Identification. It is a form of electronic tagging. A tag is attached to an object then radio waves are used to transfer information to a reader. They are a lot like bar codes except a reader does not have to be in its line of sight to read the tag.
