PROBLEM TO BE SOLVED: To improve processing performance.SOLUTION: A sequence processing device performs the following processes: the sequence processing device refers to a storage part in which a function sequentially performed in each of a plurality of separate sequences that can be performed as sequence processes, and the necessity of process of connection to or disconnection from an IC card or IC card reader/writer are related to each other and stored; then the processing device determines the necessity of a connection or disconnection process based on a sequence having the same sequence portion as is finished to a called function; next, the device performs the called function without performing a connecting or disconnecting process when determining both the connecting and disconnecting processes are unnecessary, and performs the connecting or disconnecting process and then the called function when determining the connecting or disconnecting process is necessary. |
