20140084063 | IC CARD, PORTABLE ELECTRONIC DEVICE, AND READER/WRITER - An IC card of an embodiment is provided with a receiver to receive a first command transmitted from an external device, a determining processor to determine whether or not the first command is a switching request command to request switching the IC card from a passive mode to an active mode, a switching processor to switch oneself from the passive mode to the active mode, when the first command is the switching request command, an identification information acquiring processor to acquire identification information of other IC card existing in a communicable range of the external device from the switching request command, a command generating processor to generate a second command which includes the identification information acquired by the identification information acquiring processor so as to make the other IC card execute processing, and a command transmitter to transmit the second command to the other IC card. | 03-27-2014 |
20150082111 | PORTABLE ELECTRONIC DEVICE AND IC CARD PROCESSING DEVICE - According to an embodiment, an IC card includes a communication section and a control section. The control section divides data which is transmitted to the external device. Moreover, the control section transmits a divided data portion to which an error detection code is given, to the external device through the communication section intermittently so as to make a predetermined non-transmission period. Moreover, the control section detects an error notice showing a failure in receiving divided data from the external device in the predetermined period. Furthermore, the control section retransmits the divided data portion to which the error detection code is given transmitted last after detecting the error notice. | 03-19-2015 |
20160071001 | IC CARD, PORTABLE TERMINAL, AND PORTABLE ELECTRONIC APPARATUS - An IC card includes a communication unit and a controller. The communication unit can communicate with one communication destination by a plurality of interfaces including a first interface and a second interface. The controller processes a command received by the communication unit, and makes the communication unit transmit a response to the command. In a case where the first interface becomes unavailable after the communication unit receives the command by the first interface until the communication unit transmits the response to the command, the controller makes the communication unit transmit a response containing discontinuation information indicating that the transmission of the response to the command received by the first interface is discontinued by the second interface. | 03-10-2016 |
