Abstract
A radio-type transmitting device capable of transmitting information other than information in an internal memory is provided. A RFID tag includes a encoding circuit for digitalizing receiving sensitivity of a radio wave sent from an external transmitting/receiving apparatus and then sending the digitalized receiving sensitivity to the external transmitting/receiving apparatus. Thus, the external transmitting/receiving apparatus can obtain a distance between the external transmitting/receiving apparatus and the RFID tag based on received sensitivity information.
