When in order to enable the use of a plurality of applications (AP1 to AP3) simultaneously, preparation commands, having identifiers attached, are provided according to the respective applications and working areas for the respective applications are secured inside a RAM (134). By providing a verification command having a specific identifier, a verification process concerning a specific application is performed and a verification result is stored in the corresponding application working area. This verification result is used until the completion of a communication session. To make a specific application execute a desired process, a process executing command that designates an identifier attached to the corresponding application is provided. Adequate security can be ensured and yet a series of linked processes can be performed smoothly while switching among a plurality of application programs in the same communication session. <IMAGE>
