FIG. 3 shows a factory delivery management system using the IC card of FIG.

When the truck 22 comes in front of the gate 24, the delivery person 26 who gets off the truck 22 inserts the card 10 into the IC reader 28 attached to the gate 24. The keyword data for reading sent from the host computer 30 of the factory through the IC reader 28 is input from the input / output terminal 12 of the card 10, and the keyword data is compared with the data read from the memory 18 in the control unit 20 in the card 10. After confirming the read safety, data is read from the input / output terminal 12 of the card 10. The data read from the card 10 is, for example, the name of the delivery company, the items to be delivered today, the quantity, and the like. The host computer 30 stores the name of the vendor who will deliver today from the memory 32.
The item, quantity, etc. are read and compared with the data read from the card 10. When the data match and it is confirmed that the truck is to be delivered, the host computer 30 sends a control signal to the gate 24 and the gate 24 is opened.

The truck 22 passes through the gate 24 and enters the factory,
At 36, the deliverer 26 presents the card 10 to the guard 34.
The visible image display section 14 of the card 10 displays the name of the delivery person or a predetermined code, and the guard 34 visually checks the visible image display section 14 to confirm the delivery person 26 and carry in the product. to approve.

When the deliverer 26 unloads the product from the truck 22, the receiving worker 38 causes the barcode reader 42 to read the barcode attached to the loaded / unloaded product 40. Also a card
The barcode displayed on the barcode display unit 16 of 10 is similarly read by the barcode reader 42. The bar code data of the delivered product read by the bar code reader 42 and the bar code data of the card 10 are sent to the host computer 30, and are compared with the data sent from the memory 32 in the host computer 30, and the delivery error is found. Check if there is no. After that, the delivery person 26 makes a card 10
Is inserted into the IC reader / writer 44, the host computer
The data sent from 30 is written into the memory 18 of the card 10. That is, the delivered product name, quantity, etc. are recorded. Further, this data is displayed on the visible image display unit 14 of the card 10, and the delivery person 26 checks this and confirms whether the delivered product 40 and the written data match.

In this way, the memory 18 of the card 10 carried by the deliverer 26
The delivered data is written in, and the undelivered data is corrected by this. At this time, the next scheduled delivery data is displayed on the visible image display unit 14 and the barcode display unit 16. The delivery person 26 visually confirms the next delivery schedule displayed on the image display unit 14 and heads to the next delivery destination. The delivery person delivers the product by the same operation at the next delivery destination factory. Therefore, by the card 10 carried by the deliverer 26,
It is possible to manage delivery of 26 items and delivery destinations.

In the above system, the opening / closing control of the gate 24 may be performed by reading the bar code displayed on the bar code display unit 16 by the bar code reader. Also, a person may check the visible information displayed on the visible image display unit 14. Similarly, the visual check of the guard 34 may be checked by an IC reader / writer or a bar code reader, or the barcode reading and checking by the bar code reader 42 may be performed by an IC reader / writer or visual check.

As described above, the card 10 of this embodiment can be used for both reading and writing by the IC reader / writer 28 and 44, reading by the bar code reader 42, and checking by human eyes. It can be applied to various devices and systems.

FIG. 4 shows an example of an inventory management system using the IC card of FIG.

First, the truck 50 delivers to the factory 100. When the product 52 is unloaded from the truck 50, the factory worker 10
2 attaches the card 10 to the IC reader / writer 54. Worker 102
Confirm the type and quantity of the delivered product, and input the data from the operation unit of the IC reader / writer 54. The input data is written in the memory 18 of the card 10. In this case, in order to prevent unauthorized rewriting of the data in the memory 18 of the card 10, for example, encrypted data is input by the operator 102 and compared with the code read from the memory 18 in the control unit 20 of the card 10. Memory after checking the match
Rewrite 18 data. The bar code of the delivered product 52 may be read by a bar code reader and this data may be written in the memory 18 of the card 10. Alternatively, data may be read from a similar card (not shown) owned by the deliverer by an IC reader / writer, a bar code reader, etc., and written in the memory 18 of the card 10 held by the factory.

Next, when truck 60 delivers to factory 100,
Similarly, the data of the delivered product 62 is stored in the memory 18 of the card 10.
Written in.

Similarly, delivery data of the truck 70 to the factory 100 is written in the memory 18.

On the other hand, when the product 82 is shipped from the factory 100 by the truck 80, the bar code attached to the shipped product 82 is read by the bar code reader 56, the card 10 is attached to the IC reader / writer 54, and the product 82 is shipped. Write data to memory 18 of card 10. The control unit 20 of the card 10 compares the written data of the shipped product 82 with the data of the stock product stored in the memory 18, deletes the matching one from the stock data, and stores it as the data of the shipped product. .

In this way, the memory 18 of the card 10 always accurately stores the data of the stock product at that time. Since the stock product data includes information necessary for management such as supplier name, product type, quantity, price, etc., appropriate stock management can be performed. For example, at the time of shipping, when the type and quantity of the product to be shipped are input to the card 10 from the IC reader / writer 54, the control unit 20 compares the data stored in the memory 18 and appropriately selects the product to be shipped next. be able to. That is, for example, from the data such as product delivery date, price, supplier name, etc.,
Determine which product is suitable for shipping. By displaying the product name, quantity, etc. to be shipped determined in this way on the visible image display unit 14 and the bar code display unit 16, the operator can visually confirm at the time of shipping or read by a bar code reader for confirmation. You can

As shown in the above embodiment, the IC card of the present invention is
In addition to reading and writing with an IC card reader / writer, data can also be read with a bar code reader or visually. Therefore, it can be used for various existing systems using these means.

For example, in a system using only an IC card reader / writer, there is a drawback that the operation of inserting the card into the reader becomes complicated when reading data by contact type, and the radio interference in the factory when reading data by non-contact type. In some cases, the data may not be readable. On the other hand, according to the present invention, since other reading means can be used as necessary, these problems can be solved. Moreover, since it can be applied to various existing systems as described above, a card can be used without newly providing an IC reader / writer, for example, in a place where only a barcode reading device is provided.

Further, since the data is managed by carrying the card 10 accumulating the data, the terminal for writing or reading the data does not necessarily have to be connected online, and can be applied to an offline system.

Although the visible image display unit 14 and the bar code display unit 16 are provided on the front surface of the card in the above embodiment, either one of the display units may be provided on the back surface of the card. Alternatively, only one display unit may be provided and either the visible image or the bar code may be selected and displayed by the screen display switching key provided on the surface of the card. In this case, a visible image may be displayed on the display unit when the operator visually confirms it, and a barcode may be displayed on the display unit when the image is read by the barcode reader.
In addition to the liquid crystal display described above, a magnetic powder type label in which magnetic powder is filled in microcapsules can be used for the display unit.

Further, the delivery management system and the inventory management system described above are examples of the use of the IC card according to the present invention, and it goes without saying that the IC card according to the present invention can be applied to various uses other than these. Nor.

Effect According to the present invention, since both the visible image and the bar code are displayed on the display section of the card, the information from the card can be confirmed by any of the IC card reader, the bar code reader, and the eye. Therefore, it can be used in various systems using all or any of these and has a wide range of applications. Moreover, the visible image and bar code displayed on the display unit are rewritable in correspondence with the information read from the integrated circuit, and the keywords stored in the memory of the integrated circuit and input through the input / output terminals are used. The control unit compares the data with the data, and after the safety is confirmed, the data can be displayed. Therefore, the visible image and the barcode are also highly safe.
