An RFID tag-reading notification apparatus which is capable of alerting a user by notifying the user that information has been or is going to be read from an RFID tag by a third party, without tailoring the RFID tag. A receiver section receives one of radio waves generated by an RFID reader and a signal transmitted from at least one RFID tag having received the radio waves. When the receiver section receives at least one of the radio waves and the signal, the notification apparatus outputs a notification signal indicative of reading of information from the RFID tag by the RFID reader.
