摘要
A stationary proximity wireless communication apparatus has an electromagnetic-wave transmitting and receiving part comprising a first indicator that indicates a zone to place a portable proximity wireless communication apparatus and an antenna that is installed in the zone to emit electromagnetic waves having directivity in a direction of a recommended optimum position suitable to place the portable proximity wireless communication apparatus in the zone from a position different from the recommended optimum position, and a wireless communication part configured to perform modulation and demodulation processes of electromagnetic waves transmitted and received at the antenna.
