Typically, a reader communicates with a tag, that holds digital information in a microchip; however, there are chipless forms of RFID tags that use material to reflect back a portion of the radio waves beamed at them.

2. A system that reads or writes data to RF tags that provide identification and other information pertaining to the object to which the tag is attached.

The tags have storage capacity for at least an identification number.
