DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card terminal device used in a store in a distribution / retail market.

[0002]

2. Description of the Related Art In the distribution and retail markets, settlement using a credit card is carried out in addition to settlement by cash. Credit card (hereinafter simply referred to as card)
In order to carry out payment using a card, it is necessary to prepare a card terminal device for reading information stored in the card and inputting a payment amount and the like.

[0003] In a store such as a department store, which has a large number of sales floors, in order to execute settlement processing for each sales floor,
A card terminal device is installed at each counter. When these card terminal devices obtain information necessary for the payment processing, they perform communication with a host system that centrally manages the usage status of the card and the like to complete the payment processing. Communication with the host system is centrally controlled by a higher-level device installed in the store, like the card terminal device. Each card terminal device,
Communication control with the host device is performed without being aware of the host system of each card issuing company.

FIG. 2 shows a conceptual diagram of a conventional card transaction system. The card transaction system shown in the figure is an A-D host system 1a provided for each of the card issuers A-D.
-1d, a common network 2, a communication line 3, a host device 4, a local communication line 5, and n card terminal devices T1, T2,... Tn.

The A to D host systems 1a to 1d are each composed of a host computer or the like installed at a data management facility of a card issuing company. The common network 2 includes a dedicated line for performing communication between the A to C host systems 1a to 1c and the host device 4 based on a protocol determined between the A to C host systems 1a to 1c. Is what is done. The communication line 3 communicates with the D host system 1d and the host device 4 based on a communication procedure (protocol) unique to the D host system 1d.
It is composed of a public line for performing communication between the devices.

[0006] The host device 4 includes card terminal devices T1 to Tn.
And a communication control device for performing communication control between the common network 2 and the communication line 3 (A to D host systems 1a to 1d), that is, protocol control. Card terminal T1~Tn the card reader for reading the data stored on the card C, a keyboard for inputting such settlement processing amount, more will row displays various data display device, further higher-level device 4 And a communication control device for executing a protocol process accompanying the communication with the communication device.

By the way, the card C stores system identification information composed of numerical information and the like for specifying the issuing company. Based on this system identification information, the host device 4 communicates with the host to be communicated. System (protocol)
To identify.

The operation procedure of the card transaction system having the above configuration will be described with reference to FIG. FIG. 3 is a flowchart according to a conventional operation procedure. For example, A
Card C issued by company A that manages host system 1a
Is mounted on the card terminal device T1, and the contents of the card C are read by the card terminal device T1 (step S1). Further, the clerk operating the card terminal device T1 inputs data such as the amount of money for the settlement processing, and gives an instruction to execute communication (step S2).

The card terminal device T1 generates transmission data to be transmitted to the host device 4 (step S3), and performs local communication between the host device 4 and the card terminal devices T1 to Tn according to a protocol determined. Is carried out with the host device 4 via the local communication line 5 (step S
4).

Upon receiving the data from the card terminal device T1, the host device 4 recognizes the system identification information set in the received data and specifies a host system to be communicated with (step S5). When the specification of the host system is completed, this host system (A host system 1a)
It generates transmission data corresponding to a protocol for realizing communication with the A host system 1a (step S6), and performs communication with the A host system 1a according to a protocol (common protocol) using the common network 2 (step S7).

In the B and C host systems 1b and 1c, communication by a common protocol is performed in a similar procedure. Further, with respect to the D host system 1d, communication based on a unique protocol using the communication line 3 is performed.

[0012]

As described above, in order to realize communication with a plurality of host systems having different protocols, the higher-level device 4 supports each protocol control and each protocol. Generate transmission data
carry out. However, in addition to multiple card terminal devices,
Its sometimes card transaction system introduced in the case of providing a location 4
However, there has been a problem that the cost increases and the installation space of the host device 4 must be secured. The present invention has been made in view of the above points, and has made protocol control that enables communication with each host system.
An object is to provide a card terminal device that can be directly executed .
