Abstract: An electronic timepiece includes a radio wave receiver, a communication unit, a memory and a processor. The radio wave receiver receives radio waves from positioning satellites. The communication unit communicates with an external device. The memory stores a program and predicted positional information on the positioning satellites. Based on the program stored in the memory, the processor shifts the timepiece between a normal operation state and a power saving state in which operation of the timepiece is restricted, depending on a status of the timepiece. In response to an elapsed time from a valid period of the predicted positional information exceeding a predetermined reference time during the power saving state, the processor causes the communication unit to receive updated data of the predicted positional information and other information from the external device when shifting the timepiece from the power saving state to the normal operation state.

Abstract: An electronic terminal capable of using a function of payment includes a wearing detector, a communicator, and a processor. The wearing detector detects whether the electronic terminal is worn by a user. The communicator communicates with a wireless communication apparatus via near field communication. The processor changes, based on information that is obtained by the wearing detector and the communicator, whether to enable or disable use of the function of payment.

Abstract: In a pairing establishment process, a controller (220) of a central (200) notifies a peripheral of the application identification information on the central (200). The controller (220) of the central (200) stores the device identification information on the peripheral received therefrom in a ROM (240). The application identification information is information to identify an application (that is, software) owned by the central (200). The application is to perform various communications with the peripheral.

Abstract: A wireless communication device includes a wireless communication unit, a storage unit and a processor. The wireless communication unit performs near field communication with another wireless communication device. The storage unit stores an other-device address which is identification information of said another wireless communication device and which is acquired through the wireless communication unit. The processor updates an own-device address which is identification information of the wireless communication device, when receiving an instruction for excluding the other-device address from a connection destination of the near field communication.
