The purpose of the present invention is to deliver information from an information delivery apparatus by a simple operation while protecting personal information. A wearable device (30) generates a temporary identifier (ID), generates an encrypted user ID, and transmits the temporary ID and the encrypted user ID to a shop system (40). The shop system (40) receives the temporary ID and the encrypted user ID, transmits a temporary ID corresponding to the received temporary ID and the encrypted user ID to a server (20), and transmits the temporary ID transmitted by an identifier transmitting unit (46) and information about waiting status to the server (20). The server (20) stores the user ID in association with an information delivery destination for the user ID, receives the encrypted user ID and the temporary ID, links the temporary ID to the information delivery destination for the user ID, receives the temporary ID and the information about waiting status, and transmits the information about waiting status to the information delivery destination for the user ID linked to the temporary ID. |
