摘要:
There is provided a wireless communication device that includes a first communication portion that performs non-contact communication with an other wireless communication device and receives unit specific data indicating the other wireless communication device's communication function; a second communication portion that can communicate wirelessly faster than the first communication portion; a determination portion that determines, based on the unit specific data, whether the other wireless communication device's communication function is compatible with the second communication portion; and a format conversion portion that converts a format of transmission data that is transmitted to the other wireless communication device to a format that reduces the volume of the transmission data. If the determination portion determines that the other wireless communication device's communication function is not compatible with the second communication portion, the first communication portion transmits the transmission data to the other wireless communication device in the converted data format.
