Control device and method for controlling control device
An unwanted process is prevented from being performed due to near field communication based on a process performed via an antenna which is not intended by a user. An information processing apparatus ( 1 ) includes a communication antenna determination unit ( 22 ) configured to, when a proximity state of an NFC terminal ( 10 ) to an NFC antenna ( 12 ) continues, determines that the NFC antenna ( 12 ) is an NFC antenna ( 12 ) that performs near field communication for executing a prescribed process.
1. A control device configured to control a communication apparatus including a plurality of antennas for performing near field communication with an information communication terminal, the control device including:
a continuation determination unit configured to, as to an antenna which is included in the plurality of antennas and which the information communication terminal is in contact with or proximity to, determine whether or not a contact or proximity state of the information communication terminal continues, the continuation determination unit being configured to, in case of presence of an antenna at which a variation of a current value measured at each of the plurality of antennas from a reference value by a prescribed value or more continues for a prescribed time, determine that the contact or proximity state of the information communication terminal continues at the antenna; and
a communication antenna determination unit configured to, when the continuation determination unit determines that the contact or proximity state of the information communication terminal continues, determine that the antenna to which the information communication terminal is in proximity is an antenna which performs near field communication for executing a prescribed process.
2. The control device according to claim 1 , wherein
the communication antenna determination unit is configured to, in case of presence of a plurality of antennas at which the variation continues for the prescribed time, determine that an antenna whose variation of the current is largest is an antenna that performs near field communication with the information communication terminal.
3. A method for controlling a control device configured to control a communication apparatus including a plurality of antennas for performing near field communication with an information communication terminal, the method includes:
a continuation determination step of determining, as to an antenna which is included in the plurality of antennas and which the information communication terminal is in contact with or proximity to, in case of presence of an antenna at which a variation of a current value measured at each of the plurality of antennas from a reference value by a prescribed value or more continues for a prescribed time, that a contact or proximity state of the information communication terminal continues; and
a communication antenna determination step of, when the continuation determination step determines that the contact or proximity state of the information communication terminal continues, determining that the antenna to which the information communication terminal is in proximity is an antenna which performs near field communication for executing a prescribed process.
4. The method according to claim 3 , wherein in the communication antenna determination step, in case of presence of a plurality of antennas at which the variation continues for the prescribed time, it is determined that an antenna whose variation of the current is largest is an antenna that performs near field communication with the information communication terminal.
