Abstract
Abstract An IC card (6) comprises a read only memory (ROM) (2) in which data specifying a financial body and a stored program for processing procedures are stored, a writable and readable random access memory (RAM) (3), and a central processing unit (CPU) (1) for writing or reading out the data and/or program. When, in a transaction processing, a customer inserts his IC card (6) into a terminal (16), the terminal (16) first reads out the financial body specifying data from the ROM 2. If the data as read out is correct, the terminal (16) further generates a signal indicating that the required transaction is possible and provides the signal to the CPU 1 in the IC card, where the stored program for processing procedures is read out from the ROM 2. A transaction is performed in accordance with the read program. If and when no stored program is stored in the ROM 2, the terminal (16) indicates an impossible transaction through a CRT (19) to inform a customer of the fact. The ROM (2) may store a plurality of stored programs for transaction processing procedures, in which case a customer has to select a desired program through an operation of a keyboard (20) in the terminal (16). If and when a version number of the read stored program does not coincide with a version number of the terminal (16), the program is executed after the version number of the read stored program is renewed.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
51 words
An integrated circuit card comprising: data storage means (2) including a first storage area for storing data specifying a financial body and a second storage area for storing at least one program for transaction processing procedures; and means (1) for reading out the storage contents stored in said data storage means.
Claim 2
Dependent Claim
51 words
An integrated circuit card comprising: data storage means (2) including a first storage area for storing data specifying a financial body and a second storage area for storing at least one program for transaction processing procedures; and means (1) for reading out the storage contents stored in said data storage means.
Claim 3
Dependent Claim
190 words
A financial transaction processing system comprising: an integrated circuit card (6) for use in financial transaction processing, said integrated circuit card including first data storage means (2) having a first storage area for storing data specifying a financial body and a second storage area for storing at least one program for transaction processing procedures, and reading means (1) for reading out the storage contents stored in said data storage means; and a terminal (16) for communicating with said integrated circuit card, said terminal including means (Step S3 and Step S4) responsive to receipt of said financial body specifying data read out from said first storage means for determining whether said financial body specifying data coincides with the data specifying a financial body to which said terminal belongs and for generating, upon coincidence, a signal indicating that a requested transaction is possible to apply the signal to said reading means of said integrated circuit card, said reading means of said integrated circuit card being responsive to said possible transaction indicating signal for reading out said program for transaction processing procedures from said second storage area to send it to said terminal.
Claim 4
Dependent Claim
190 words
A financial transaction processing system comprising: an integrated circuit card (6) for use in financial transaction processing, said integrated circuit card including first data storage means (2) having a first storage area for storing data specifying a financial body and a second storage area for storing at least one program for transaction processing procedures, and reading means (1) for reading out the storage contents stored in said data storage means; and a terminal (16) for communicating with said integrated circuit card, said terminal including means (Step S3 and Step S4) responsive to receipt of said financial body specifying data read out from said first storage means for determining whether said financial body specifying data coincides with the data specifying a financial body to which said terminal belongs and for generating, upon coincidence, a signal indicating that a requested transaction is possible to apply the signal to said reading means of said integrated circuit card, said reading means of said integrated circuit card being responsive to said possible transaction indicating signal for reading out said program for transaction processing procedures from said second storage area to send it to said terminal.
Claim 5
Dependent Claim
54 words
A financial transaction processing system in accordance with claim 2, wherein said terminal further includes impossible transaction indicating means (Step S5 and Step S8) for indicating that the transaction requested by a customer is impossible when no program for transaction processing procedures is stored in said second storage area of said integrated circuit card.
Claim 6
Dependent Claim
89 words
A financial transaction processing system in accordance with claim 2, wherein said second storage area stores a plurality of programs for transaction processing procedures, said terminal further includes program designating means (Step S19) for designating a desired program for transaction processing procedure to be executed, from said plurality of programs, and said reading means of said integrated circuit card reads out the program designated by said program designating means from said plurality of programs stored in said second storage area and sends the program as read to said terminal.
Claim 7
Dependent Claim
79 words
A financial transaction processing system in accordance with claim 4, wherein each of said plurality of programs contains data specifying its own program, said program designating means includes data inputting means (20) for inputting the data specifying a program to be executed, and said reading means of said integrated circuit card reads out the program containing the data coinciding with the data inputted by said data inputting means, from said plurality of programs stored in said second storage area.
Claim 8
Dependent Claim
160 words
A financial transaction processing system in accordance with claim 2, wherein said first data storage means further includes a third storage area for storing first data specifying said programs for transaction processing procedures, and a fourth storage area for storing second data indicating a version of said program and said terminal further includes second data storage means having a fifth storage area in which third data specifying at least one program for transaction processing procedures to be able to be executed is stored and a sixth storage area in which fourth data indicating a version of said at least one program for transaction processing procedures, and program executing means (Step S41, Step S42 and Step S43) for executing said program for transaction processing procedures read out by said reading means when said first data read out by said reading means coincides with said third data and said second data read out by said reading means coincides with said fourth data.
Claim 9
Dependent Claim
135 words
A financial transaction processing system in accordance with claim 6, wherein said second data storage means further includes a seventh storage area in which data used for renewing program from a version indicated by said second data to a version indicated by said fourth data is stored; and said terminal further includes program rewriting means (Step S41, Step S42 and Step S51) for rewriting said program for transaction processing procedures read out by said reading means to a program having a version indicated by said fourth data, using said data used for renewing program, when said first data read out by said reading means coincides with said third data and said second data read out by said reading means does not coincide with said fourth data, and said program executing means executes said rewritten program.
