RFID (Radio Frequency IDentification) is the use of a wireless non contact system that uses radio frequency electromagnetic fields to transfer data from a tag attached to an object for the purpose of automatic identification and tracking. Radio Frequency IDentification (RFID) is the quintessential pervasive computing technology. Touted as the replacement for traditional barcodes, RFID's wireless identification capabilities promise to revolutionize the authors' industrial, commercial, and medical experiences. The heart of the utility is that RFID makes gathering information about physical objects easy.
