Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data storage device that preliminarily stores data stored in an IC card.

[Conventional technology]

In recent years, systems that use cards to conduct product transactions and eliminate the need for direct cash payments have been attracting attention. Cards used in such systems include, for example, magnetic cards with a magnetic sheet attached that are used as cash cards in deposit systems such as banks, and data cards as disclosed in Japanese Patent Laid-Open No. 58-28761. I equipped with IC chips such as processing units and memory
C cards are known and are provided with a data memory so that desired data can be stored.

However, since magnetic cards use magnetic sheets as data memory, and ICs and cards use RAM (random access memory) as data memory, the storage capacity of RAM is limited by the capacity of the battery that holds the data. Therefore, in both cases, restrictions were added to the data stored, making them inconvenient to use.

In response, the present applicant previously proposed an IC card that uses non-volatile FROM (programmable read-only memory) as data memory. This IC card does not require a battery to hold data in the data memory, and therefore the storage capacity of the data memory can be made sufficiently large.

[Problem that the invention seeks to solve]

By the way, if such an IC card is lost, the data stored on it will be completely lost, and the
If the C card is damaged by bending or the like, the IC card becomes unusable and cannot be used to write or read data.

In order to eliminate such inconveniences, it is conceivable to preliminarily store data in a terminal device that writes and reads data on an IC card.

As a result, when the IC card is lost or damaged and becomes unusable, the IC card can be regenerated using the data stored in the terminal.

However, since terminals handle a large number of IC cards, preliminarily storing the data of each IC card would require a huge amount of memory, making it large and expensive. This increases the burden placed on the terminal and impairs its original data processing function. Furthermore, if the terminal device malfunctions, there is a risk that a large amount of data may be lost. On the other hand, in card systems, data is generally preliminarily stored in a central computer, and this data may be used to play back the IC car 1'. This increases the burden and reduces the activity of the card system.

An object of the present invention is to solve such problems, and to provide data storage that allows data stored in an IC card to be stored safely and reliably without increasing the burden on the card system. There is a device to suggest.

Means for Solving Problem C] To this end, the present invention comprises a processing device and a memory,
When a C card is inserted, data is read from the IC card and written into the memory. This allows the data on the IC card to be saved individually independent of the card system, and if the IC card is lost or damaged, the data stored in the memory can be used to store the data on the card that is not used by the card system. IC cards can be played back using a playback-only device.

〔Example〕

First, an example of an IC card will be briefly explained with reference to FIG.
A circuit board provided with input/output devices consisting of 38. ~3. is card body 1
configured to be exposed on the surface of the The processing bag W4 has a program memory that stores processing programs, and the data memory 5 stores necessary data such as deposit details and passwords (i.e., when this IC card is used as a cash card). password) will be memorized.

When an IC card with such a configuration is installed in a terminal,
The terminal device and the circuit on the circuit board 2 are electrically connected through the connection terminals 31 to 38, and power supply voltage, clock pulses, etc. are supplied from the terminal device.

The processing device 4 operates according to the above-mentioned processing program, and verifies the password entered manually from the terminal, or reads the password from the data memory and sends it to the terminal in order to verify the password at the terminal, and reads the password from the data memory and sends it to the terminal. After determining that the terminal is used normally, data from the terminal is written to the data memo I75 and data is read from the data memory 5 to the terminal.

An IC card basically has the above configuration, and also:
Although the above operation is performed, an embodiment of the present invention that preliminarily stores data stored in such an IC card is as follows.
This will be explained below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a data storage device according to the present invention, in which 6 is the data storage device of this embodiment, 7 is a processing device, 8 is a memory, 9 is an input/output device, and 10 is a power source. 1 is the IC card shown second.

In the figure, a processing device 7 has a program memory storing a program, a clock pulse generator, etc., and an input/output device 9 has connection terminals 3. It consists of connection terminals corresponding to 38 (Fig. 2). Memory 8 is IC card data memory 5
It consists of an electrically erasable non-volatile memory of the same capacity as (FIG. 2).

The data storage device 6 is configured such that an IC card 11 can be attached thereto, and when this ICC card 11 is attached, each connection terminal forming the input/output device 9 is connected to the corresponding connection terminal 3. Contact with ~38, data storage device 6
is electrically connected to the IC card 11.

A power supply voltage is applied to the power supply connection terminal of the input/output device 9 from the power supply device 10 via the processing device 7 (or directly). Supplies power supply voltage to Similarly, clock pulses are supplied from the processing device 7 to the IC card 11 via the input/output device 9. Along with this, the processing device 4 (FIG. 2) of the IC card 11
As described above, the processing program starts the operation, and at the same time, a signal indicating that the operation has started is supplied to the processing device 7 via the input/output device 9. Along with this, the processing device 7 starts operating according to the program.

Next, the processing device 7 reads the password from the memory 8 and supplies it to the IC card 11 via the input/output device 9. I
As described above, the C card 11 verifies the password, and if the password supplied from the input/output device W9 is correct, the processing device 7 is informed of this fact.

Next, the processing device 7 sends a data read command signal to the IC card 11 and waits for a data write state. IC
In the card 11, data is sequentially read out from the data memory 5 (FIG. 2) based on this data succession command signal, and this data is sent to the data storage device 6. Therefore, in the data storage device 6, this data is written into the memory 8 by the processing device 7. I
When reading of all addresses in the data memory 5 of the C card 11 is completed and all data stored in the IC card 11 is written to the memory 8, the data storage device 6 and the IC card 11 stop operating. In this way, I
All data stored in the C card 11 is stored in the memory 8.

Further, if it is determined by password verification that the password from the input/output device 9 is incorrect, the processing word W7 is notified of this, and the processing device 7 stops its operation.

Therefore, no data is read from the IC card 11.

The password may be verified in the processing device 7. In this case, the processing device 4 (FIG. 2) of the IC card 11 reads the password from the data memory 5 (FIG. 2) and sends it to the processing device 7 at the same time as the operation starts. The processing device 7 reads the password from the memory 8 and compares it with the password from the IC card 11, and when the two match, sends a data read command signal to the IC card 11.

In this way, all data stored on the IC card is transferred and stored in the data storage device 6, but if the IC card is lost or damaged and becomes unusable, a dedicated terminal or other Thus, the data stored in the data storage bag M6 can be written to a new IC card, and the IC card corresponding to this data can be reproduced. Also, IC
By inserting this IC card into the data storage device 6 every time you insert the card into the terminal and write data, the data stored in the data storage device 6 will always be the same as the data currently stored on the IC card. The data will be saved. In addition, by verifying the password, the data storage bag N
Since data can be written to the IC card 6, the data storage device 6 is dedicated to one IC card.
Therefore, even if another password is attached, the data written in the data storage bag W6 will not be destroyed, and data storage will be safe and real. Furthermore, I
By making the terminal for reproducing the C card also operate by verifying the password, it is possible to prevent unauthorized reading of data from the data storage device 6, thereby ensuring data confidentiality.

Next, a case where the IC card 11 is used as a bank passbook will be explained.

When depositing or withdrawing money at a bank, the IC card 11 is attached to a terminal provided at the bank and predetermined operations are performed.
At this time, data regarding the deposit is written, rewritten, updated, or erased in the IC card 11. After the data has been changed, when the IC card 11 is inserted into the data storage device 6, all the data stored in the IC card 11 is automatically transferred to the memory 8 of the data storage device 6, as described above. will be written to. In this case, since all addresses in the data memory 5 (FIG. 2) of the IC card are read, the memory 8 of the data storage device 6
Writing is performed to all addresses in the IC card 11, and therefore only the data stored in the IC card 11 is written into the memory 8.

If the IC card 11 is lost or damaged, the IC card just before it was lost or damaged can be regenerated by taking the data storage device 6 to a place (for example, a bank) equipped with a terminal for reproducing IC cards. I can have it done for you.

The data storage device 6 may normally be separate from the IC card, but it may also be a case that accommodates the IC card. When using an IC card case as the data storage device 6, the IC card is always stored in the IC card case when not being used in the terminal.
After using the card in a terminal, the changed data of the IC card is always written to the IC card case, and the data that is exactly the same as the data currently stored on the IC card is always saved in the IC card case. .

FIG. 3 is a plan view showing such an IC card case, where 12 is the case body, 13 is an insertion slot, and parts corresponding to those in FIG. 1 are given the same reference numerals.

In FIG. 3, a processing device 7, a memory 8, and a power supply device 10 such as a solar cell are fitted into the case body 12, and each connection terminal of the input/output device 9 is exposed on the inner surface of the case body 12. It is set up like this. The I'C card shown in FIG. 2 is inserted from the insertion slot 13 in the direction of the arrow, and when fully inserted, each terminal 3 of the IC card
1 to all come into contact with corresponding connection terminals of the input/output bag W9 of the case body 12, respectively, and the IC card and the IC card case are electrically connected. As a result, the data stored in the data memory 5 of the IC card is automatically written to the memory 8 of the IC card case, as described above.

In the embodiments described above, when the memory 8 is configured with an electrically erasable nonvolatile memory, it is necessary to supply power supply voltage from the power supply device 10 when writing, reading, erasing data, etc. However, other than that, no power supply voltage is required. However, a volatile memory can be used as the memory 8, and in this case, the memory 8 naturally requires power backup.

Also, if the IC card itself has a built-in power supply,
Although the power supply bag W10 can be omitted in the data storage device 6, if the memory 8 is a volatile memory, a backup power supply device for the memory 8 is required.

〔Effect of the invention〕

As explained above, according to the present invention, data stored in an IC card can be saved independently of the card system, and even if the IC card is lost or damaged,
It is possible to play back IC cards without putting a burden on the card system, and since the writing and reading of data in memory is managed by the processing device, data can be stored safely and reliably. Many excellent effects can be obtained, such as the ability to maintain confidentiality.
