摘要：
A communication apparatus includes: an antenna; a first communication means that performs near field communication with a non-contact card via the antenna; a photodetecting means that is provided near the antenna and detects an amount of incoming light; and a near field communication control means that activates the first communication means when the amount of incoming light becomes less than a predetermined threshold value, the communication apparatus being driven by a battery.
