Radio Frequency Identification in my opinion is a violation of privacy. It uses radio waves to identify merchandise or people. Most vendors do not deactivate it when you purchase a product,so your product is basically ready to transmit the information embedded on the chip. They have antenna's on them to transmit the signals to a reader that converts radio waves into digital information.That can then be processed by a computer. RFID has been around since 1970 RFID has problems around metal and water.
