RFID TAG HAVING CONTROL SWITCH OF ELECTRIC CURRENT FLOW

摘要

PURPOSE: An RFID tag having a control switch of an electric current flow is provided to prevent the leakage of the information stored at a tag chip by installing an electric switch between a chip and an antenna. CONSTITUTION: An RFID(Radio Frequency IDentification) includes a current control switch(3) between a tag antenna(2) and a tag chip(1), and the current control switch shorts the antenna near the tag chip. The current flow control switch is connected to the tag chip, and a capacitor or an inductor is installed at the one end of the current flow control switch through serial connection.
