1. A communication terminal, comprising:
- a first communication unit that communicates wirelessly in a passive mode in which the first communication unit communicates by receiving power from an external apparatus, or an active mode in which the first communication unit communicates by providing power;
a second communication unit that communicates wirelessly as a control apparatus or as a controlled apparatus;
determining the mode of the first communication unit connecting to an other communication apparatus; and
activating the second communication unit as either the control apparatus or the controlled apparatus in a case where the first communication unit operated in the passive mode connected with the other communication apparatus, and activates the second communication unit as either the control apparatus or the controlled apparatus in a case where the first communication unit operated in the active mode connected with the other communication apparatus so that the second communication unit is activated differently from an activated one in the case where the first communication unit operated in the passive mode connected with the other communication apparatus, wherein the second communication unit starts a communication with the other communication apparatus operated as the controlled apparatus in a case where the the second communication unit is activated as the control apparatus, and starts a communication with the other communication apparatus operated as the control apparatus in a case where the the second communication unit is activated as the controlled apparatus.

Abstract
A communication terminal includes a first communication unit which has a power supply function by electromagnetic induction and writes or reads information in an active or passive mode, and a second communication unit having a communication capability higher than that of the first communication unit. A mode in which the first communication unit is functioning, the active mode or the passive mode, is determined. Communication via the second communication unit is controlled based on the determination result.
