Abstract

The invention relates to a portable electronic device and a recording medium. The portable electronic device having a power supply unit and an IC chip that conducts wireless communication with a reader / writer and operates when power is supplied from the power supply unit includes a first determining unit that determines whether or not the portable electronic device, in a state in which the IC chip is operating moved, according to a result of detection by a sensor to detect movement, a second determining unit that determines whether or not a signal from an opposing device equipped with the reader / writer was received, and a power control unit that conducts control to allow a state in which power is supplied to the IC chip from the power supply unit when the first determining unit determines that the portable electronic device did not move and the second determining unit determines that the signal was received.

Description

Field of Invention [0001] Embodiments discussed herein relate to portable electronic devices and recording media. Background technique [0002] RFID (Radio Frequency Identification) technology that utilizes short-range wireless communication between readers (R / W) to perform ID (identity) information transmission is generally known in the art. Generally, an RFID integrated circuit (IC) chip is mounted in an electronic device such as a mobile terminal device so that wireless communication can be performed between a reader / writer arranged outside the mobile terminal device and other corresponding devices. Such wireless communication is not limited to communication between readers and writers, and wireless communication is also frequently performed between mobile terminal devices composed of corresponding mobile terminal devices equipped with RFID IC chips. The mobile terminal device may be, for example, a mobile phone, a PDA (Personal Digital Assistant) or a portable PC (Perso...
