Description: The present invention relates to a system for performing credit transactions including a cash register and a center. Credit cards and bank cards have been introduced into use for the payment of accommodation charges at hotels, motels and like accommodation facilities. At these facilities, the guest bearing such a card is requested to present the card when checking in for the clerk to check the guest for his eligibility and credit. For such checking, the front clerk at the hotel or the like usually makes a telephone call to the credit company or the center of the bank concerned to make inquiries as to the credit standing of the guest and credit limit set for the guest. However, this method of checking by telephone has the drawback of failing to give satisfactory service because the guest bearing the card and other guests are obliged to wait for a long period of time required for the inquiry. On the other hand, electronic cash registers are placed into use at accommodation facilities for cash registration. From US-A-3749 887 there is known a cash register comprising a keyboard for cash registration, a card reader for reading the data recorded in a card, a communication control unit for making communication with a center provided with a file having stored therein information as to customers. At the center a message is automatically answered and information relating to the credit standing and other facts regarding the card holders or customer is sent to the cash register. An object of the present invention is to use an electronic cash register for automatically making inquiries as to the credit standing, credit limit, etc. of guests who use a card so as to assure savings in labor and improved service. The invention is as claimed in claim 1. The present invention is especially useful for hotels, motels and like accommodation facilities, eliminating the necessity of keeping the guest waiting for a long period of time, assuring improved service and permitting the hotel clerk to devote himself to the front service other than credit inquiries. Fig. 1 is an overall block diagram showing a credit inquiry system with use of an electronic cash register (ECR); Fig. 2 is a block diagram showing the construction of the ECR; Fig. 3 shows the keyboard of the ECR; Fig. 4 shows the contents of a memory included in the ECR; Fig. 5 shows part of the contents of a CIF provided at the center of a credit company; Fig. 6 shows part of the contents of a trouble file at the center; and Fig. 7 is a flow chart showing the procedure to be followed at the front of a hotel. Fig. 1 shows the overall construction of a credit transaction system. A hotel or motel 1 is provided with an electronic cash register (ECR) 4. Through a telephone network 5, the ECR 4 is connected to the center 2 of a credit company and/or the center 3 of a bank. Besides these, there may be a credit investigation company having such a center. The center 2 is provided with a host CPU 20 for processing credit inquiries, a customer information file (CIF) 21 and a trouble file 22. Similarly, the center 3 is provided with a host CPU 30, and a CIF and trouble file 31. Although not shown, the centers 2 and 3 are provided with a communication control unit to make communication with ECR's 4. Fig. 2 schematically shows the construction of the ECR 4. The ECR 4 is controlled by a CPU 10 which has a ROM 11 storing a program therefor, and a memory (RAM) 12 for storing data for cash registration processing and data for credit inquiries. The ECR 4, serving as an input-output device under the control of the CPU 10, comprises a card reader 13 for reading the data recorded in cards, a display 14 for showing data as to cash registration and data as to credit inquiries a printer 16 for printing such data, a keyboard 15 for entering instructions for performing these operations and for entering data, and a keyboard 17 for entering a secret number. Preferably the keyboard 17 is connected to the ECR 4 by a cord so as to be operated only by customers. The keyboard 17 need not be provided when the secret number is not checked by the ECR 4 and/or the centers 2, 3 (especially the center 3). The ECR 4 is further provided with a communication control unit 18 for making communication with the centers 2 and 3. The unit 18 includes an automatic dial circuit, modem, etc. The cards to be used for the ECR 4 include, for example, credit cards and bank cards. The credit card, which is issued from the credit company to a member thereof, has recorded therein the member's number, the code of the credit company, etc. The bank card, which is issued from the bank to a person having an account at the bank, can be used for making payments like the credit card. The bank card has recorded therein the account number, bank code, branch code, secret number, etc. Fig. 3 shows the keyboard 15 of the ECR 4 for illustrative purposes. The keyboard 15 has a mode switch 41, center specifying keys 42, numerical keys 43 and function keys 44. As is generally well known with ECR's, the mode switch 41 is used for selecting the operation mode of the ECR 4. The center specifying keys 42 represent the shortened dial numbers of centers. The function keys 44 include a "DIAL" key, "CIF REQUEST" key and "REFERENCE" key, in addition to those generally used in ECR's. Fig. 4 shows the arrangement of data in the memory 12 of the ECR 4. The memory 12 has an area for storing data for cash registration processing (ECR data), an area for storing the number for identifying the ECR (terminal identification number or TID), an area providing a table of reference telephone numbers, areas for use as outgoing and incoming data buffers, an area for storing card data, etc. The telephone number table stores the telephone numbers of centers specified by the shortened dial numbers #1 to #5 in corresponding relation thereto. The telephone number of a center is registered, for example, by a key input sequence following the setting of the mode switch 41 to "PROGRAM". Fig. 4 shows an example wherein the telephone number 06-123-4567 of a certain center is registered as the shortened dial number #1. First, the function key "MENU", numerical key "1" and function key "CASH/TOTAL" are depressed in the order mentioned to select a reference telephone number registration menu. Next, the function key "DIAL" is depressed, and then the center specifiying key "#1" is depressed to select the shortened dial number #1. Finally, the numerical keys "0", "6", "1", "2", "3", "4", "5", "6", "7" and function key "CASH/TOTAL" are depressed in the order mentioned, whereby the number is registered. The reference telephone number table can be such that the telephone numbers of the centers are stored in corresponding relation to the numbers identifying the centers, such as the codes of the credit companies or banks. Since the card data includes the code of a credit company or bank, the center concerned can be automatically dialed with reference to the card data in this case, without the necessity of entering the shortened dial number with use of a key 42. Fig. 5 shows an example of CIF 21 at the center 2 of the credit company. The CIF 21 has stored therein details of information as to the individual members of the company under the corresponding members' numbers. The information includes credit limits. Fig. 6 shows an example of trouble file 22 at the center 2. The trouble file 22 is adapted to store data as to the credit cards which have been invalidated. The data includes the reason for the invalidation of each of such cards under the member's number concerned. The CIF and trouble file 31 at the center 3 of the bank are similar to those described above, except that the account number will be used as a customer identifying code instead of the member's number. The deposit balance of the customer, etc. are also stored in the CIF. The limit on credit to be afforded can be determined according to the sums of deposits in time and ordinary deposit accounts, etc. Fig. 7 shows the procedure of credit inquiry to be executed when the ECR 4 is installed on the front desk of a hotel. In the case illustrated, the ECR communicates with the center of a credit company. First, the guest delivers his credit card to the front clerk (step 51). The credit card is inserted into the card reader 13 of the ECR 4 by the clerk (step 52), so that the data recorded in the card is read by the card reader 13 and stored in the card data area of the memory 12. When required, the secret number is entered by the guest with use of the keyboard 17 (step 53) and checked with reference to the secret number read from the card. When one number matches the other, next step follows, whereas if they are not in match, the display 14 shows the result, and no further steps are performed. The center may have the secret number stored in its CIF, and the secret number keyed in or read from the card may be transmitted to the center, where the two numbers will be compared for matching. The expected amount of payment corresponding to the accommodation charge is keyed in by the front clerk with the keyboard 15 (step 54). The amount of payment is also stored in the memory 12. The credit card indicates the credit company concerned, and when one of the keys 42 is depressed to specify that credit company (step 55), the corresponding telephone number is read out from the telephone number table in the memory 12. The communication control unit 18 automatically dials the corresponding center to connect the telephone line. Alternatively the clerk may manually dial the center with numerical keys 43. Further alternatively the telephone number of the credit company may be retrieved from the table with reference to the code of the company in the card data for automatic dialing as already stated. In this case, the function key "REFERENCE" will be used for giving an instruction for starting automatic dialing. In any way, when the ECR 4 is connected to the center to be referred to, a message edited in the outgoing data buffer of the memory 12 and containing the terminal identification number (TID), card data and amount of payment is sent to the center. At the center 2, the trouble file 22 is searched with reference to the member's number in the card data sent from the ECR 4 to check whether the member's number is registered in the file 22. If the number is not registered in the trouble file 22, the CIF 21 is searched, and the amount of payment forwarded is compared with the credit limit set for the member concerned. A message is then sent from the center 2 to the ECR 4 concerned which message contains the check result as to whether the card is invalid and whether the amount of payment is in excess of the credit limit. The message is stored in the incoming data buffer of the memory 12. The data in the incoming data buffer is shown on the display 14 and/or is printed by the printer 16. The display or print tells the clerk whether the card is invalid (step 57) and whether the amount of payment is in excess of the credit limit (step 58). A further step is therefore taken according to the result. More specifically, if the card is not invalid, with the sum of payment not in excess of the credit limit, it is judged that the payment can be made with the credit card, allowing the guest to check in (step 59). However, even if the card is invalid or the sum of payment is in excess of the credit limit, the present embodiment is so adapted that the clerk can check the guest for his credit standing with reference to the details of personal data of the guest which will be sent from the center (step 60). In this case, the clerk depresses the function key "CIF REQUEST" on the keyboard 15, whereupon the ECR 4 is connected to the center 2 again, and a message requesting detailed personal data is sent from the ECR 4 to the center 2. Upon receipt of the message, the center 2 searches the CIF 21 to edit a message covering all or part of personal data of the member concerned and sends the message to the ECR 4 (step 61). This communication is of course carried out in the same manner as in step 56. The personal data forwarded from the center is shown on the display 14. The clerk can judge whether the transaction with the card is acceptable, generally with reference to the display, especially such items of personal data as the date of application for membership, the member's name, the member's employer, the period of residence of the member at the present address (code), the member's married/umarried code, the member's annual income (classification code), the member's financial standing (code which may indicate dishonest practice, if any), the name of membership family, etc. (Step 62.) When the transaction is found acceptable, a check-in procedure follows (step 59). If the transaction is found unacceptable, the clerk asks the guest whether he agrees to make the payment in cash (step 63). If he agrees, check-in follows, but if otherwise, he is of course unable to check in (step 64). In the case where the report from the center 2 indicates that the card is invalid or that the sum of payment is in excess of the credit limit, the front clerk can of course proceed to the step of checking whether the guest agrees to a cash transaction, without making reference to the detailed personal data at the center 2. Although the foregoing description is given of the case wherein the ECR communicates with the center of a credit company, the communcation between the ECR and a bank is of course made in the same manner as above.
