The invention discloses an intelligent information identification adopting method using an ultrahigh and ultralow frequency signal transmission way. The method is characterized in that a controller and an information card are provided and comprises the following steps that: S1, the controller emits a low-frequency signal regularly or after being triggered, and the information card enters a low-frequency signal zone and is activated by the low-frequency signal; S2, the information card activates… CONTINUE READING
