To determine candidates for product purchase in electronic commerce more easily when a user purchases an attracting product through electronic commerce, the server (14A) includes a retrieval API (164A). The retrieval API (164A) receives and analyzes identifying information from a user terminal (12A) having a function of acquiring identifying information for identifying a product and thereby identifies one or more products from the identifying information. Then, the retrieval API (164A) reads one or more product sales information corresponding to the identified one or more products from a product database (168) that stores product sales information related to sales of products. The retrieval API (164A) then stores the read one or more product sales information as a retrieval history into a retrieval history database (170) and transmits the one or more product sales information to the user terminal (12A) to be displayed as candidate product information on the user terminal (12A). |
