Title:
NFC COMMUNICATION APPARATUS AND METHOD FOR CONTROLLING SAME
Document Type and Number:
WIPO Patent Application WO/2012/011289
Kind Code:
A1
Abstract:
This NFC communication device comprises: an antenna unit (101) that receives radio waves from a reader-writer device (20) through near field communication; a first power supply unit (102) that uses the received radio waves to generate a power; a second power supply unit (104) that is a driving power supply; a power supply status holding unit (107) that holds information indicating a power supply status of the second power supply unit (104); a near field communication unit (606) that near-field-communicates the information indicating the power supply status of the second power supply unit (104) via the antenna unit (101); and a power supply switch unit (103) that switches the power, which is used to drive the near field communication unit (606) and the power supply status holding unit (107), from the second power supply unit (104) to the first power supply unit (102) in accordance with the power supply status of the second power supply unit (104). When the power supply of the second power supply unit (104) exhibits an off power supply state, the power supply switch unit (103) switches the power from the second power supply unit (104) to the first power supply unit (102).
