A user is guided with a simple configuration so that near field communication is performed. An information processing device (1) includes an NFC antenna (520) configured to perform near field communication with an NFC terminal (100), and a display unit (53) configured to display a guide region (Ai). The guide region (Ai) serves as a guide for a communication-enabling region. The display unit (53) displays the guide region (Ai) such that the guide region (Ai) is included in the communication-enabling region (B) and the guide region (Ai) is smaller than the communication-enabling region (B).
