Description

[Detailed description of the invention]

[Industrial Field of Application] The present invention relates to a credit card processing device that displays on a credit terminal the details of an abnormal condition occurring in a store control section or a loop control section. [Prior Art] When a large number of electronic cash registers must be placed in each sales floor, such as in a department store or large-scale supermarket, each electronic cash register and one loop control unit are installed in each sales floor. Each loop control section is connected to a closed loop, and each loop control section is connected to one store control section as a whole. In such a system, when selling products with a credit card, the membership number (card
Card information, such as a personal identification code (No.), a personal identification code, and a company code indicating the card issuing company, is incorporated into the sales permission inquiry message and transmitted to the store control unit via the loop control unit. The store control unit searches the received card information in a sales permission information file for each card stored on a magnetic disk or the like, and determines whether sales are permitted or not by the corresponding card. Then, the sales permission/non-permission information is incorporated into the response message,
A reply is sent via the loop control section to the electronic cash register that sent the inquiry message. Each electronic cash register that receives the response message displays information on sales permission or disapproval on, for example, a display unit. The cashier then checks the displayed content and determines whether or not to sell the product using the credit card. [Problems to be Solved by the Invention] However, in the credit card processing device that inquires of the store control unit as to whether or not credit card sales are permitted, the following problems occur. . In other words, even if card information is incorporated into an inquiry message from each electronic cash register and transmitted to the store control unit via each loop control unit, there will be no communication between the electronic cash register and the loop control unit or between the loop control unit.・Even if the store control units go offline and become unresponsive, or an error occurs in one of the control units and an error occurs in the received message, it is difficult to determine what caused these abnormal conditions. It could not be determined from what was displayed on the display of the electronic cash register. Therefore, when such an abnormal condition occurs, there is a problem in that inspection and repair work cannot be carried out quickly. As a result, the system had to be stopped for a long time. The present invention allows the loop control unit and the credit terminal to detect the content of the abnormal state between the store control unit and the loop control unit, respectively, and displays the content on the credit terminal, thereby making it possible to immediately grasp the content of the abnormality. An object of the present invention is to provide a credit card processing device that can speed up inspection and repair work. [Means for Solving the Problems] In order to solve the above problems, the present invention incorporates card information input from each credit terminal into a sales permission inquiry message when a sales transaction using a credit card occurs. The loop control unit that controls each credit terminal is relayed to the store control unit that stores sales permission information for each credit card, and the response message to the inquiry message output from this store control unit is sent to the loop control unit. In a credit card processing device that relays a message to a credit terminal and displays the response result on the credit terminal, a loop control section detects an abnormal state of the store control section based on a response message from the store control section. When the store control unit abnormal state detection means detects the abnormal state of the store control unit, the store control unit abnormal state detection means transmits the details of the store control unit abnormal state to the credit terminal that sent the inquiry message. When each credit terminal device receives an abnormal message from the loop control section, it has a store control section abnormal state display means for displaying the contents of the abnormal state, and a loop control section abnormal state display means for displaying the contents of the abnormal state. A loop control section abnormal state detection means detects an abnormal state of the loop control section based on a response message from the control section, and when the loop control section abnormal state detection means detects an abnormal state of the loop control section, the abnormal state is detected. and loop control section abnormal state display means for displaying the contents. [Operation] According to the credit card processing device configured in this way, when an abnormal state occurs in the store control section, this abnormal state is detected by the loop control section, and the contents of the abnormal state are incorporated into the abnormal message. is sent to the credit terminal. Furthermore, if an abnormal condition occurs in the loop control section, this abnormal condition can be detected by the credit terminal itself. Therefore, when an abnormal condition occurs in a credit card terminal, it is possible to distinguish whether the abnormal condition has occurred in the store control section or the loop control section, and the details of the abnormal condition can be displayed together with the location where the abnormal condition has occurred. be done. [Example] An example of the present invention will be described below with reference to the drawings.
