Sensor tag and method for authenticating for the same

Sensor tag device and the authentication method is disclosed, the present invention provides a sensor tag attached to the article, to sense the surrounding environment sensor element for outputting a value; And when the sensor tag is using a current value sensed by the initial value sensed by the sensor unit the current sensor unit when attached to an article is determined that a physical change in the sensor tag including a control unit for processing locked out of the sensor tag the features.
