<p>Provided is a technique of correcting the tuning frequency of the antenna of a wireless communication device to a suitable frequency regardless of the communication environment with a reader/writer device, thereby further stabilizing communication between the wireless communication device and the reader/writer device. The wireless communication device (100) communicates wirelessly with the reader/writer device (900) in a contactless manner. The wireless communication device (100) is provided with a resonant circuit (16) that receives an electromagnetic signal from the reader/writer device (900), a proximity sensor (12) for detecting proximity to the reader/writer device (900), a temperature detection circuit (13) for measuring the temperature of the communication environment of the wireless communication device (100), and a control circuit (19) for controlling communication with the reader/writer device (900). The control circuit (19) corrects the tuning frequency of the resonant circuit (16) on the basis of at least any of a distance parameter that indicates the distance to the reader/writer device (900) and a temperature parameter of the communication environment of the wireless communication device.</p> |
