Abstract:
1. A communication device comprising: a first master communication means which performs a first communication which is proximity communication at a first communication speed; a second master communication means which performs a second communication which is proximity communication at a second communication speed faster than the first communication speed; an electrical power transmission means where a slave communication device which receives a supply of electrical power to perform the second communication transmits electrical power to perform the second communication using wireless electrical power transmission; and a monitoring means which monitors electrical power supplied to the slave communication device using the wireless electrical power transmission, wherein the first master communication means receives configuration information including a maximum electrical power consumption, which the slave communication device consumes in the second communication, from the slave communication device using the first communication, the electrical power transmission means begins wireless electrical power transmission after the first communication with the slave communication device begins, the second master communication means begins the second communication with the slave communication device after the wireless electrical power transmission has begun, and the electrical power transmission means stops the wireless electrical power transmission in a case when the electrical power monitored by the monitoring means exceeds a threshold set from the maximum electrical power consumption.
