Abstract: The present invention provides a reception system, a reception method, and a non-transitory computer-readable medium storing a program that are capable of identifying a guest. The reception system (100) includes a face photo information check unit (1), and a reception terminal (2). When the reception terminal (2) receives an input indicating an application for a check-in of a guest (GS1), the face photo information check unit (1) checks passport-face-photo-at-check-in-time information scanned from a passport (P1) at the time of check-in, with face-photo-at-check-in-time information through photographing the guest (GS1) at the time of check-in. When the passport-face-photo-at-check-in-time information and the face-photo-at-check-in-time information indicate a same person as a result of checking by the face photo information check unit (1), the reception terminal (2) displays information on a room reserved by the guest (GS1), and issues a card key for the room reserved by the guest (GS1).
