Abstract

PURPOSE:To save the labor for reentering data after working by temporarily storing data stored in an IC card when working exchange of the battery of the IC card or the like. CONSTITUTION:When working the exchange of battery of the IC card or the like, the IC card is set too the temporary storage device for the data of the IC card. In response to the command of a reading command means, the data stored in the IC card is read by a data reading means and stored in a data storing means. Then, after working the exchange of battery or the like the IC card is set to the temporary storage device again. In response to the command of a transmission command means, the data stored in the data storing means is transmitted to the set IC card by a data transmission means. The data stored in the temporary storage device is transmitted to the IC card and thereafter erased, so that the data of the IC card cannot be stolen by others.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for temporarily storing data stored in an IC card.

[Prior Art] Magnetic cards such as so-called cash cards and credit cards have been widely used for transactions at banks, credit companies, etc., but in recent years, IC cards have been proposed as an alternative to these magnetic cards. has been done.

As this IC card, for example, JP-A-60-196
There is one shown in Publication No. 876. This IC card consists of a data storage means, a data processing means, a data input means, and a data display means.
A transaction is executed by inputting transaction data such as the type of transaction and transaction amount, and transmitting the transaction data stored in this IC card to a terminal device at the time of transaction.

Therefore, according to this IC card, various transaction data can be reliably entered and stored in one's own IC card before going to a bank etc., so the operating procedures of the terminal device are greatly reduced, and transaction data can be stored in the IC card. Processing efficiency can be increased.

[Problems to be Solved by the Invention] A general IC card has a built-in battery, and the data storage means, data processing means, etc. are driven by this battery.

Therefore, when replacing the battery, the data stored in the data storage means is lost, and after the battery is replaced, various data must be re-entered into the IC card, which is time-consuming. .

In particular, if there is a large amount of data stored in the IC card before the battery is replaced, there is a risk that the data will be forgotten when re-entering unless it is written down, which requires additional effort. Furthermore, if the data stored on the IC card is kept in a memo or the like, there is a risk that the memo or the like will be stolen by another person and the data will be misused.

Therefore, the main purpose of the present invention is to temporarily store data stored in an IC card during work such as replacing the battery of the IC card, and to transmit the data to the IC card after the battery is replaced. The next step is to provide a device that prevents that data from being misused.

[Means for solving the problem] The temporary storage device for IC card data according to the present invention includes:
a reading command means for commanding the reading of data stored in the IC card; a transmission command means for commanding the transmission of the data to the IC card; and data reading means for reading the data. The IC card data temporary storage device includes a data storage means for storing data read by the data reading means, and a data storage means for storing the data read by the data reading means; The data transmitting means is provided with a data sending means for sending and storing the data on the card, and a data erasing means for erasing the data stored in the data storage means after the data is sent by the data sending means.

[Function] When performing work such as replacing the battery of an IC card, before doing so, first store the IC card as a temporary storage device for data on the IC card according to the present invention (hereinafter abbreviated as temporary storage device). ).

In response to the command from the reading command means, the data reading means reads the data stored in the IC card and stores it in the data storage means.

After the work such as battery replacement is completed, the IC card is set in this temporary storage device again. In response to a command from the sending command means, the data sending means transfers the data stored in the data storage means to the set I.
It is sent to the C card and stored.

In this way, the data of the IC card that is temporarily stored in this temporary storage device during work such as battery replacement is sent to the IC card after the work, and the data that is stored in this temporary storage device is Since the data is erased after being sent to the IC card, there is no possibility that the data on the IC card will be stolen by someone else.

If the IC card 10 is set, the IC
Storage area 132 of ROM 13 of card 10 (Figure 5)
The KEY code stored in the device is read and this device 1
It is determined whether the key code matches the KEY code stored in the storage area 32 (FIG. 6) of the ROM 3 (step 86).

If both KEY codes do not match or if the KEY code is not read from the set card, the operation ends.

If both KEY codes match, then the number 10 stored in the storage area 133 of the ROM 13 of the IC card 10 is read (step S7). and,
It is determined whether the read tD number matches the ID number stored in the storage area 41 of the RAM 4 of this device 1 (step 88).

If both ID numbers do not match, the operation ends.

If both [0 numbers match, the RA of this device 1
The data stored in the storage area 42 of M4 is sent to the IC card 10 and stored in the storage area 141 of the RAM 14 of the IC card 10 (step 9). Next, the data stored in the storage area 42 of the RAM 4 of this device 1 is erased (step 510).

In this way, data temporarily stored in the device 1 during work such as battery replacement of the IC card 10 is returned to the IC card 10 after the work.

As mentioned above, this device @1 does not send data if the ID numbers do not match, so there is no risk that the data temporarily stored in this device 1 will be stolen using another card. .

Furthermore, since the data stored in this device 1 is erased after the data is sent, there is no risk that the data will be stolen by someone else.

In the above embodiment, by setting the IC card 10 in this device @1, a command to read the data stored in the IC card 10 is issued. A command key may be provided, and reading of data may be commanded by pressing this key.
