A light receiver of a communication apparatus receives light from an LED that emits light based on a light-emission pattern defined by an ID. An ID acquirer specifies the light-emission pattern from light received by the light receiver and acquires the ID. A transceiver transmits the acquired ID to a service server that stores an ID/URL table associating together the ID and a URL of information relating to equipment equipped with the LED, and receives a corresponding URL. An information acquirer acquires the information relating to the equipment based on the URL received by the transceiver. |
