Description

[Detailed Description of the Invention] C. Industrial Application Field] The present invention relates to exchange control using an electronic exchange, and for example, when an automatic international telephone charge card used for international calls is used by a corresponding subscriber. The present invention relates to a card checking device that checks whether a card exists or not.

[Conventional technology]

When making international calls, it is convenient to use an automatic international call charge card. In Japan, this international telephone bill automatic debit card is issued by KDD (Kokusai Telegraph and Telephone Corporation).
It is called an international credit card. In countries other than Japan, it is also called an international credit card. If you purchase an international credit card and use it to make an international call to a desired phone number in a country other than Japan, the cost of the call will be automatically deducted from the cardholder's bank account, for example. It has become. Therefore, the card owner is free to make international calls anytime and anywhere.

However, as long as you have the card, a third party other than the card owner can use it to freely make international calls. Such misuse by a third party puts the card owner at an unfair disadvantage.

To prevent this, when purchasing an international credit card, the purchaser must register a personal identification number, etc., in the same way as a bank's Cashini card. By comparing this PIN number, it was checked whether the international credit card belonged to the subscriber.

[Problem that the invention seeks to solve]

However, the conventional method of checking international credit cards is to check whether the person using the international credit card is the applicable subscriber, but whether the person subscribed to the card in Japan or in a country other than Japan. There was no function added to check whether this is the case. For this reason, for example, an international credit card purchased in a country other than Japan could not be used in Japan. - Therefore, an object of the present invention is to provide a card checking device that allows an international credit card registered in a country other than Japan to be used in Japan.

[Means for solving problems]

In the present invention, (1) a storage means for storing registered country name information indicating the name of the country in which an automatic international call charge card is registered, in which the telephone charge is automatically deducted from a bank account when making an international call; (ii) A calling means by which a subscriber who has registered an automatic international telephone charge debit card uses this card to call the desired country and transmits the name of the desired country, and (iii) calls made from this calling means. a communication means for transmitting desired country name information; and (iv)
a comparison means for respectively comparing the registered country name information read from the storage means and the desired country name information; and (v) if the desired country name information matches the registered country name information by the comparison means, the communication means is connected to the exchange of the desired country. The card checking device is equipped with a circuit exchanger for checking the card. Here, both the registered country name information and the desired country name information are composed of decimal number strings that are different for each subscriber, and for each piece of information, the corresponding numbers are specified as the first and second digits, respectively. It may be provided with a discriminating means that performs calculations according to the four arithmetic calculation methods and determines that the subscriber belongs to the same subscriber if the calculation results match.

That is, in the present invention, since the registered country name information of a registered international credit card is checked using an identification information storage means such as a disk provided in a telephone exchange, it is possible to determine in which country the international credit card is registered. It is possible to determine whether As a result, international credit cards registered in countries other than Japan can be used in Japan.

〔Example〕

The present invention will be described in detail with reference to Examples below.

FIG. 1 shows a method of checking an international credit card using a card checking device according to an embodiment of the present invention when a telephone line is connected from Japan to a desired destination country, for example. be. The international automatic telephone exchange 1o is an electronic exchange that checks a subscriber's international credit card and connects a telephone line to a desired destination country.

In the international automatic telephone exchange 10, subscribers have telephones 11-1, 11-2, . . . installed in Japan, for example.
A plurality of incoming trunks 12-L 12-2... and a plurality of outgoing trunks 13-1, 13-2... for transmitting and receiving requested signals using any one of the It is equipped. In addition, international automatic telephone exchange lO
is provided with a check disk 14 storing a plurality of check items for checking subscriber numbers of registered international credit cards, and a switch 15 for selecting and connecting a plurality of lines.

Of these, the check disk 14 contains algorithms and
A check table 15 is arranged.

Algorithm check table 16 includes BELL (Bell Laboratories) standard credit card format check parameters and CCITT (International Telegraph and Telephone Consultative Committee) to identify registered international credit cards.
Standard credit card format check parameters are stored respectively. These check parameters are registered for international credit cards issued in up to eight countries.

The switch 15 checks each country in which the international credit card is issued based on the check items stored in the check disk 14. As a result, if it is determined that the international credit card is valid, that is, it belongs to the applicable subscriber, the exchange 17-1, 17-2, etc. installed in the desired country other than Japan is used. The line is now connected to...

A case will be described below in which the line connected to the private trunk 12-1 is connected to the exchange 17-1 of foreign country A by the switch 15.

When a subscriber makes an international call, when the subscriber inserts an international credit card issued in a predetermined country into the international credit card slot (not shown) of the telephone 11-1, the telephone registers the international credit card. The registered registration number information 18 is input to the switch 15 through the human trunk 12-1. At this time, algorithm check table 16
Two check parameters stored in BE
The registration number information 18 is checked based on the format check parameter 19 of the LL standard credit card or the format check parameter 21 of the CCITT standard credit card.

The registration number information 18 is a numeric string expressed in decimal notation, and the number of digits varies depending on the country of issue, so it is checked for each country. For example, international credit cards registered in North American countries are checked based on BELL standard credit card format check parameters 19. Further, the algorithm check table 16 stores an operation check instruction (command) 22 and a validity period check instruction 23, respectively. Among these, the arithmetic check instruction 22 is configured to add, multiply, and divide the first and second most significant digits of the number string constituting the registration number information 18 according to four predetermined arithmetic operations. Arithmetic check instruction 22 is used to identify whether the international credit card belongs to the subscriber in question. Other validity period check instructions 23 are as follows:
This command is used to check the validity period of an international credit card.

In this way, between the switch 15 and the algorithm/check table 16, the two format check parameters 19.21, the arithmetic check instruction 22, and the validity period check instruction 23 are used to check whether the international credit card belongs to the applicable subscriber. It is checked whether it is true or not.

As a result of the check, if it is determined that the international credit card belongs to the applicable subscriber, the outgoing trunk 13
Exchange of foreign country A, which is the desired partner country, by -1! ! 1
A line 24 is connected to 7-1.

If the international credit card does not belong to the subscriber, the operator sends an invalidation notification signal 25 from the switch 15 in the international automatic telephone exchange 11 through the incoming trunk 12-1 to the subscriber's telephone 11. Send back to -1. At this time, the line 24 is not connected to the outgoing trunk 13-1.

〔Effect of the invention〕

In this way, the present invention allows an international credit card registered in a country other than Japan to be used in Japan. This has the effect of improving the convenience of international credit cards.
