<P>PROBLEM TO BE SOLVED: To reliably write data on the basis of a re-performed issuing operation, even when communication with a writing processing server is disconnected. <P>SOLUTION: After an issuing processing server transmits the data so as to update an issuing status to an issued state, even when the communication with the writing processing server (S154-157) by a portable terminal in order to write the data received by the portable terminal (S153) is disconnected, since a processing status is updated by the portable terminal into a data received state (S153a), the request of writing the data is transmitted to the writing processing server (S154) without transmitting issuing request information to the issuing processing server again (S152) when another issuing operation is received. <P>COPYRIGHT: (C)2007,JPO&INPIT |
