Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a card authentication terminal group management device, and in particular,
The present invention relates to a card authentication terminal group management device which is connected via communication lines to a plurality of card authentication terminal devices and a plurality of host computers, each of which performs credit card authentication and transaction processing when selling credit cards.

Summary of the Invention The present invention provides a card authentication terminal group management device that stores data required by a first card authentication terminal, and stores data required by the first card authentication terminal,
By transmitting the stored data to the card authentication terminal device of the tube 1 and mediating communication between the second card authentication terminal device and the second host computer, one card authentication terminal group is created. This allows multiple types of card authentication terminal devices to be connected to the management device.

Conventional Technology As is well known, with the spread of credit cards, in order to automate credit card authentication and transaction processing,
A card authentication terminal device called a CAT (Credit Authorization Terminal) has been put into practical use.

For example, in a supermarket, a CAT is installed at each sales floor. These multiple CATs are connected to a card authentication terminal group management device that manages them, and further, via this card authentication terminal group management device,
Connected to the credit card company's host computer.

By the way, the data necessary for the above-mentioned CAT credit transaction is stored in the card authentication terminal group management device.
In response to a command from each CAT, the card authentication terminal group management device sends the information to the CAT and loads it.

Problems to be Solved by the Invention However, the above-mentioned supermarkets may have various tenants, and some of these tenants may have connections with other affiliated credit companies that the supermarket is not a member of. There may be a contract. In such a case, the tenant's CAT needs to transmit data between the host computer of a different credit company than the one with which the supermarket is subscribed, so the card authentication installed at the supermarket is required. It was not possible to connect CAT to the terminal group management device.

Therefore, this invention was made to solve the above-mentioned problems. 82e! ! It is an object of the present invention to provide a card authentication terminal group management device that can connect various types of card authentication terminal devices.

Means for Solving the Problems The card authentication terminal group management device of the present invention includes a first transmission means that mediates data transmission between a first host computer and a first card authentication terminal device; a second transmission means for mediating data transmission between the host computer and the second card authentication terminal device; a storage means for storing data required by the first card authentication terminal device;
In response to receiving the data transmitted from the first host computer and required by the first card authentication terminal device, the first transmission means writes the data into the storage means and writes the data into the storage means. In response to receiving the request to send necessary data sent from the card authentication terminal device of No. 1,
Write/read υIt[1 to read necessary data from storage means
and, in response to the first reading control means reading out the necessary data from the storage means, via the first transmission means,
The necessary data is transmitted to the card authentication terminal device that requested the transmission, and in response to the second transmission means receiving the data transmitted from the second host computer, the second transmission means transmits the data as it is to the second transmission. and transmission control means for controlling transmission to any second card authentication terminal device via the means.

Operation The card authentication terminal group management device of the present invention stores data required by the first card authentication terminal device transmitted from the first host computer in the storage means, and performs any one of the first card authentication operations.

FIG. 13 explains the operation of the cluster controller according to an embodiment of the present invention! It is a ζth flow diagram.

Next, the operation of one embodiment of the present invention will be described in detail with reference to FIGS. 1 to 13.

The CPU 10 of the cluster controller 1-roller 1 is CΔT2a,
2b, is on standby until it receives a message from the first post computer 3 or the second host computer 4, and receives the message from the first or second host computer 3, 4 via the upper-side transmission unit 14; The received message is sent to the corresponding CAT2a or 2b via the lower-side transmission unit 15, but when the message from CAT2a or 2b is received, the transaction classification code included in the received message is "Other". 5'' indicating the key 315. When the CPU 10 determines that the transaction classification code is not '5'', the CPU 10 sends the message from the CΔT 2a or 2b to the corresponding first host computer 3 or second host computer 3. 4 to the post computer 4. On the other hand, when it is determined that the transaction account and minute codes are "5", it is then determined whether the classification code is '90' or not.
It is determined whether it is 91'' or 92''.

Here, if the classification code is '90', c

It waits until it receives the L telegram 70, and when it receives the DLI-telegram 70, its contents are transferred to the RAM 12 and stored. Subsequently, the processing result is transmitted to the CΔT2a, and the process returns to the initial state.

If the classification code is “91”, the CPU 10 is
DLL telegram 7 based on the data stored in AM12
0 and sends it to the relevant CAT2a via the lower transmission unit 15.
, and then return to the initial state.

If the classification code is "92", CP (Jlo) sends the DLL message 60 from CAT2fl as is to the second host computer 4. Subsequently, the CPU 10 sends the DLL message from the second host computer 4. In response to a message similar to the DLL message 7o being sent from the second host computer 4, the message is sent as is to the MCA T2b, and the process returns to the initial state.

Effects of the Invention As described above, according to the present invention, data required by the first card authentication terminal device transmitted from the first host computer is stored in the storage means, and data transmitted from the first host computer is stored in the storage means. Based on the instructions from the card authentication terminal In, the stored data is sent to the card arffi terminal device of the first card concerned, and the transmitted data sent from the second host computer is directly sent to any second card. Since the information is configured to be transmitted to the authentication terminal device, a plurality of types of card authentication terminal devices can be connected to one card authentication terminal group management device.
