Abstract
This invention executes a series of instructions to issue an IC card on a computer side which issues an IC card, previously simulates a change in the contents written into a nonvolatile memory of the IC card, and transfers the written contents to the IC card to write the same into the nonvolatile memory.
Claims15
A portable electronic medium in which application data is stored in a nonvolatile memory based on a plurality of instructions supplied from a host device by serial communication and which performs processes by use of the stored application, comprising:
- storage means for previously storing application data which is obtained by simulation based on a plurality of instructions, and which is to be stored in the nonvolatile memory, in the nonvolatile memory by use of the host device.
A portable electronic medium issuing system comprising:
- a host device, and
- a portable electronic medium which is coupled with said host device by serial communication and includes a nonvolatile memory used to store files and file control information,
- wherein said host device includes first creation means for creating a plurality of instruction messages for issuance of said portable electronic medium, second creation means for creating files and file control information obtained by simulation based on a plurality of instruction messages created by said first creation means and to be stored in a nonvolatile memory, and first transmission means for transmitting the files and file control information created by said second creation means and stored in the nonvolatile memory to said portable electronic medium by use of one message;
- and said portable electronic medium has storage means for storing files and file control information obtained by simulation based on a plurality of instructions supplied from said host device and stored in the nonvolatile memory.
A method for issuing a portable electronic medium which includes a nonvolatile memory used to store files and file control information and which is to be coupled with a host device by serial communication, comprising:
- creating a plurality of instruction messages for issuance of a portable electronic medium,
- creating files and file control information obtained by simulation based on a plurality of created instruction messages and stored in a nonvolatile memory,
- transmitting the created files and file control information stored in the nonvolatile memory to the portable electronic medium by use of one message, and
- storing the transmitted files and file control information obtained by simulation based on the plurality of instructions, and stored in the nonvolatile memory.
