Patent ID: 8064829

Claim:
A wireless communication system, comprising: a first wireless communication device; and a second wireless communication device, wherein the first wireless communication device includes a non-contact communication portion that transmits by a non-contact communication method unit specific data that indicate a communication function of the first wireless communication device, the second wireless communication device includes a first communication portion that receives the unit specific data that are transmitted from the first wireless communication device by the non-contact communication method, a second communication portion that is capable of a wireless communication at a faster communication speed than that of the non-contact communication method, a determination portion that determines, based on the unit specific data, whether the first wireless communication device is equipped with a communication function that is compatible with the wireless communication, and a format conversion portion that converts a data format of transmission data that is transmitted to the first wireless communication device to a data format that reduces a data volume of the transmission data, and, if the determination portion determines that the first wireless communication device is not equipped with the communication function that is compatible with the wireless communication, the first communication portion transmits, by the non-contact communication method, to the first wireless communication device the transmission data whose data format was converted by the format conversion portion to reduce the data volume of the transmission data.
