<p><P>PROBLEM TO BE SOLVED: To provide non-contact portable electronic equipment, a non-contact IC card and non-contact IC card system for efficiently transmitting and receiving data without generating any reception error or an unreceived status at an external device side. <P>SOLUTION: A non-contact IC card is configured to receive an electromagnetic wave to be transmitted from a non-contact card reader/writer, and to generate an operating voltage with the received electromagnetic wave for operation, and to execute processing corresponding to a command to be transmitted from the non-contact card reader/writer, and to transmit the processing result to the non-contact card reader/writer. When transmitting a processing result corresponding to the command to the non-contact card reader/writer, the non-contact IC card calculates the time required for processing for the command received from the non-contact card reader/writer, and when the calculated processing time is longer than a predetermined time, transmits the calculated processing time to the non-contact card reader/writer as data. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
