Radio Frequency Identification (RFID)

RFID is a technology that transmits the identity of a person or object wirelessly using radio waves. RFID technology consists of a tag (used on the object) and a reader that processes the information being sent out by the tag. RFID can be read through a human body, clothing, etc. An example of RFID is EZ Pass. In the future, it is likely that RFID will replace UPC (Universal Product Code). This would mean no more waiting online at the supermarket- the reader will be able to know every item you have just by the radio waves being sent out by the RFID tags.
