READER/WRITER DEVICE FOR NONCONTACT IC CARD, COMMUNICATION SYSTEM AND NONCONTACT COMMUNICATION METHOD

WIPO Patent Application WO/2008/059564

A1

A reader/writer device performs noncontact communication with a noncontact IC card section (400) to which power is supplied from a power storage section (310) of a portable terminal (300) whereupon the card section is mounted. In the reader/writer device (100), a noncontact communication section (110) transmits and receives information to and from the IC card section (400) by noncontact communication, and a noncontact charging section (120) supplies power to the power storage section (310) in noncontact manner. When noncontact communication with the IC card section (400) cannot be performed by controlling the noncontact communication section (110), a noncontact communication/charge control section (130) controls the noncontact charging section (120) to charge the power storage section (310) of the portable terminal (300) in noncontact manner, then, controls the noncontact communication section (110) again to perform noncontact communication.
