There is provided an information processing device to detect the position of the RFID tag performing wireless communication with a high degree of accuracy and perform display according to the position of the RFID tag, the information processing device including: a first information acquiring unit configured to acquire identification information of an RFID tag on a basis of communication with the RFID tag according to near field wireless communication; and a second information acquiring unit configured to acquire position information of the RFID tag in a method different from a method used by the first information acquiring unit. The position information is transmitted to an external device.

Information processing device and information processing method

The present technology relates to a communication device, a communication method, an integrated circuit, and an electronic instrument, which are capable of reducing a manufacturing cost of a communication device having both functions of an RF tag and reader/writer or an electronic instrument equipped with the communication device. A transmitting circuit transmits transmission data to a communication target by performing load modulation of changing an impedance of an antenna unit according to the transmission data using a first carrier generated in the antenna unit when the transmitting circuit operates in a first operation mode in which the transmitting circuit operates as an RFID reader/writer is performed, and the transmitting circuit transmits the transmission data to the RFID reader/writer by performing the load modulation of changing the impedance of the antenna unit according to the transmission data using a second carrier received by the antenna unit when the transmitting circuit operates in a second operation mode in which the transmitting circuit operates as a communication target of the RFID reader/writer is performed. For example, the present technology can be applied to a communication device having both functions of a reader/writer and an RF tag or an electronic instrument equipped with the communication device.
