Radio Frequency Identification – RFID in plain English
What if barcodes were replaced by chips that could not only be read more quickly but could have their information updated as well? And what if those chips could communicate with other devices? These chips already exist and the technology they use is called RFID – short for Radio Frequency IDentification.
RFID from wiki …
Radio-frequency identification (RFID) is the use of an object (typically referred to as an RFID tag) applied to or incorporated into a product, animal, or person for the purpose of identification and tracking using radio waves. Some tags can be read from several meters away and beyond the line of sight of the reader.
