adio frequency identification (RFID) is an enabling technology. By itself, RFID doesn't provide much value, but it does enable companies to develop applications that create value.
RFID describes systems that use radio waves to transmit an object's identity.

The antenna enables the chip to transmit whatever identification information it contains to a reader. The reader converts the radio waves from the RFID tag into digital information that software systems can use for processing.
