Abstract

PURPOSE:To easily transfer data between IC cards by judging a data transfer direction and transferring data by a connector itself. CONSTITUTION:An IC card 1a and an IC card 1b are connected through a connector 8. The connector 8 is composed of detectors 9 and 10, CPU11 and a memory 12 and a display part 13. When the card is inserted, CPU11 judges whether or not ''0'' is written at a personnel memory area B0 of one side card 1a, and when ''0'' is stored, the card is not a master card. Consequently, next, CPU11 judges whether or not ''0'' is written at other side card 1b, and when ''0'' is not written, it is judges whether or not ''1'' is written, and when ''0'' and ''1'' are not written at the card 1b, CPU11 judges that the card 1b is a master card, and data is transferred from the card 1b to the memory area A0 of the card 1a. When data transfer is completed, ''1'' is written in the memory area B0 of the card 1a, 1 is taken from the personnel of the card 1b, data transfer is completed and a card sampling display is performed at the display part 13.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to an IC card data transfer connector, in particular,
Control data transfer between IC cards! 2 (Relating to a connector for C card data transfer) that has the function of

Background of the Invention Unlike conventional magnetic cards, IC cards have at least a memory for storing data and a CPU for processing data.
It has a contact point for communicating with a terminal device.

The above-mentioned IC card has a larger storage capacity than a magnetic card, and is highly secure because it is programmed so that it cannot be easily read, so there is no fear that the stored information will be deciphered by others. It is also possible for the IC card itself to issue the request on its own initiative. from these things,
IC cards are currently widely used for various purposes.

1. If you write information for multiple people on the C card at once,
For example, it is possible to streamline the release of the rX world.

However, if this continues, multiple people will have to take the same action, causing inconvenience. To eliminate this inconvenience, it is recommended to use an IC card with data for multiple people as the parent card, and use each individual's IC card as the child card to transfer data for each person from the parent card to the child card. do it. For this purpose, a connector that controls and relays data transfer is essential.

To summarize, this invention has a function that, when two IC cards are connected, searches the memory contents of the IC cards, determines the direction of data transfer by itself, and controls and relays the data transfer. This is a connector for transferring IC card data.

The objects and other objects and features of the present invention will become more apparent from the detailed description given below with reference to the drawings.

Examples of the invention FIG. 2A is a diagram showing the structure of the IC card.

In FIG. 2A, the IC card 1 has a memory 2 that stores given data, and displays the contents of the memory 2 on a display section 4 in response to a signal given from an input terminal 3, and also switches a switch 5 to a terminal 6. It is comprised of a central processing unit (hereinafter referred to as CPU) 7 that switches to the side.

FIG. 2B is a diagram showing the internal structure of the memory 2 of the IC card 1. In FIG. 2B, the memory 2 includes an area AO for storing boarding data and an area BO for storing the number of passengers. Storage area AO further includes area A that stores the expiration date.
AO1, an area AO2 for storing the boarding station, an area AO3 for storing the getting off station, and an area AO4 for storing the adult or child.

FIG. 2C is a diagram showing the internal structure of the memory of the IC card serving as the child card. In FIG. 2C, storage areas corresponding to the memory of the parent card are indicated by the same letters. however,
When data is written to the number of people storage area BO, 1'' is written.

FIG. 1 is a diagram showing the internal configuration of an IIC card and a child IC card and their connections. In FIG. 1, an IC card 1a and an IC card 1b are connected via a connector 8. The connector 8 includes detectors 9 and 10 that detect whether or not the IC card 1a and the IC card 1b are connected, respectively, a CPU 11 that controls data transfer between the parent IC card 1a and the IC card 1b, and the operation of the CPIJll. It is composed of a memory 12 that stores reference data, and a display section 13 that displays instructions from the CPU 11 to the user.

The CPU 11 uses memory 2 of two connected IC cards.
The memory contents of a and 2b are read and it is determined which one will be the parent card (an IC card in which data for a plurality of people is written).

FIG. 3 is a flow diagram showing the data transfer operation between IC cards by the connector of FIG. 1. Below, Figure 1, 2A
2B, 2C, and 3, data transfer operations between IC cards will be described.

The detector 9.10 detects whether a card is inserted in both (810). Step 10 is repeated until both cards are inserted. When cards are inserted into both, the CPU 11 determines which card (on the detector 9 side, hereinafter referred to as the left card for convenience of explanation) 1a has 0'' written in the number of people storage area BO ( Sll). If "0°" is not stored in the storage area 80 of the memory 2a of the left card 1a, jump to step 20. "0°" is stored in the number of people storage area of the k-side card 1a, BO. If so, the left card 1a is not the parent card. Therefore, next, the other side card (for convenience of explanation, the detector 10 side,
Hereinafter, it will be referred to as the right card > ib number of people memory lower 1j 7
CPUII determines whether "°O" is written in RO (5.12). If O'' is not written in the storage area BO of the right card 1b, CP and Ul determine whether 1'' is written in the storage area BO of the right card 1b.
1 (813). 0" and '1" are stored in the storage area BO of the right card 11].
The data is transferred from the storage area AO of the right card 1b to the storage area Δ0 of the left card 1a (814). If the data transfer is not completed, "Pa1" is written in the storage area BO of the left card 1a (815). 1 is subtracted from the number of people written in the storage area BO of the right card 1b (S16). Since the data transfer has been completed, a message indicating that the card has been removed is displayed on the display section 13 of the connector 8 (817).The detector 9 and the CPU 11 determine whether the left card 1a has been removed (318).The left card 1a has been removed. Step 18 is repeated until the left card 1a is taken, then the right card 1b is taken.
Detector 10. It is determined by the CPU 11 (819). If the right card 1b is not removed,
The CPU 11 determines that the data transfer for all the people has not yet been completed, and the process returns to step 10. When the right card 1b is removed, all data transfer is completed. Here, step 12. If l Q II or 1'' is written in the storage area BO of the right card 1b in step 13, there is no need to transfer data, so the process jumps to step 17.
This is a case where the parent card and the CPU 11 determine that.

Next, the data transfer operation when the left card 1a is the parent card will be described. In step 11, left card 1a
If it is determined that a number other than ``0'' has been written in the memory area BO1, it is determined whether ``1'' is written in the memory area BO (820).Left card 1a
If "1n" is not written in the storage area BO of the right card 1b, it is determined that the left card 1aS is the parent card, and it is determined whether II OII is written in the storage area BO of the right card 1b (821). 1b storage area BO
If "'O" is written in the memory area AO of the left card 1a, the data written in the storage area AO of the left card 1a is transferred to the right card 11.
) is transferred to the storage area AO of (S22>). When the data ladder transfer is completed, 1" indicating the completion of data transfer is written in the storage area B○ of the right card 1b (S23). The storage area of the left card 1a 1 is subtracted from the number written in BO (S24).

Since the data transfer has been completed, a temporary card removal command is displayed on the display unit 13 (825>. The right card 1b is removed (S26) and the left card 1a is removed (S2).
7> is completed, all data transfer from the parent card to the child cards for the number of people is completed. If the left card 1a is not handled in step 27, it is determined that the data transfer for the number of people has not been completed, and the process returns to step 10. The above operations complete the data transfer from the parent card to the child card.

In the above embodiment, the configuration of the memory of the IC card is described for the case where multiple people have the same ride data (J1 car section, expiration date, etc.), but the memory of this IC card has the same ride data (J1 car section, expiration date, etc.). may be written in each storage area. Furthermore, it goes without saying that the type of transferred data is not limited to transportation usage data (such as ride data).

Effects of the invention As mentioned above, in this invention, [C card and I
Since the connector that relays data transfer with the C card is configured to determine the data transfer direction and perform the transfer, data transfer between the IC cards can be easily performed.
