Abstract
A data transmission arrangement for a portable data storage medium, in which messages are transmitted between an external device and a portable data storage medium at a plurality of times in response to one readout command output from the external device. When malfunction occurs during the processing in the portable data storage medium, the portable data storage medium outputs an abnormality response to the external device, and then receives a continuous data demand command from the external device. Thereafter, a status data different from the status data included in the first message is sent from the portable data storage medium to the external device. The external device recognizes this sent status data. Thereafter, the data transmission started in response to one readout command is not discontinued and additional data continuous to be transmitted.
