Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a prepaid card reading / writing device, and more particularly to a prepaid card reading / writing device with a negative value reading detection function for detecting a negative value when reading a prepaid card whose balance data is displayed with a dark color mark on the card surface. It is a thing.

[0002]

[Prior art]

 Recently, magnetic cards have become popular as prepaid cards. It has a certain feature in that it records a large amount of data and keeps the confidentiality of the data. However, since a magnetic card normally writes data to a magnetic stripe attached to a resin and then reads it magnetically, it is extremely easy to tamper with data by a magnetic writer and thus make it illegal. As you know, it is causing the problem of.

Therefore, mainly for the purpose of data tampering and fraud prevention, the balance is printed and displayed as a binary data on the surface of a card made of paper or plastic with a dark color mark, and the display is updated every time the balance is updated. Pre-paid cards with configurations have come to be used. With such a prepaid card, a balance display consisting of a series of dark-colored marks is added and printed side by side with the old balance display for each transaction.

As a prepaid card reading / writing device for reading and writing such a prepaid card, a reading mechanism for optically reading a series of dark color marks printed on the surface of the inserted prepaid card, and a reading device for reading. The control means that detects the current balance of the prepaid card from the signal, calculates the update balance after adjusting the transaction amount from this balance, and the old balance on the surface of the prepaid card as a series of dark marks. And a writing mechanism such as a printer that prints additionally on the side by side.

[0005]

Generally, in a prepaid card reading / writing device, a prepaid card balance reading error, a recording error when the balance was previously recorded, or an illegal card insertion, etc. For some reason, a negative balance may be read. However, in the prepaid card reading / writing device having the above-mentioned conventional structure in which no special countermeasure is taken, even if such an abnormality of the negative value balance occurs, it cannot be detected, and Could not be effectively eliminated.

The present invention has been made in order to solve the problem of the prior art, and its purpose is to detect and inform a negative value balance when a negative value balance is read out. It is to provide a prepaid card reading / writing device.

[0007]

[Means for Solving the Problems]

 A prepaid card reading / writing device with a negative value reading / detecting function of the present invention comprises a reading mechanism for reading balance data from a prepaid card, a writing mechanism for writing updated balance data to a prepaid card, and a memory. A prepaid card read / write device that incorporates a microcomputer that operates according to the procedure stored in the above, and stores control means for controlling the operation of each part of the device in the memory, and the microcomputer executes at least the control means. In the apparatus, a negative value detecting means for notifying when the balance data read by the reading mechanism is a negative value is provided in the memory as an execution procedure of the microcomputer.

[0008]

[Action]

 In the prepaid card read / write device with the negative value read detection function of the present invention configured as described above, the negative value detection means is activated each time the read mechanism reads the balance data, and the balance data read by the read mechanism. It is confirmed whether or not is a negative value, and if a negative value is detected, this is notified.

[0009]

【Example】

 FIG. 1 is a block diagram of an embodiment of a prepaid card reading / writing device with a negative value reading detection function of the present invention. FIG. 2 is a plan view of a prepaid card loaded in the prepaid card reading / writing device of FIG. In FIG. 1, a prepaid card reading / writing device 1 with a negative value reading detection function of the present invention comprises a microcomputer 2 for controlling the entire device and a series of dark color marks printed on the surface of an inserted prepaid card P 1. A reading mechanism 5 for reading, a writing mechanism 6 for writing the updated balance as a series of dark marks on the old balance on the surface of the prepaid card P for additional recording, and an operation program and data for the microcomputer 2 accessed by the microcomputer 2. And a power supply circuit 9 which is connected to the power supply line S and supplies power to each part of the apparatus.

Further, in the memory 3, a control means 4 executed by the microcomputer 2 is stored. The control means 4 reads the current balance of the inserted prepaid card P from the signal read by the reading mechanism 5, subtracts the transaction amount from this balance to settle, and calculates the updated balance. It is equipped with a control procedure for the operation of each part of the device. Further, the memory 3 is provided with a negative value detecting means 12 for notifying when the balance data read by the reading mechanism 5 is a negative value.

The microcomputer 2 further drives the alarm 10 and the display 11 connected to the prepaid card reading / writing device 1 as necessary when executing the procedure. The alarm 10 is composed of a buzzer or the like, and the display 11 is composed of a warning lamp or the like.

As shown in FIG. 2, the prepaid card P loaded in the prepaid card read / write device 1 with the negative value read detection function has its balance binary-divided on the surface of a paper or plastic card as shown in FIG. The data is printed and displayed with a dark color mark D, and the balance is additionally recorded and displayed every time the balance is updated. Therefore, the reading mechanism 5 preferably has an optical configuration that sends light to the card surface and reads based on the intensity of the reflected light or the transmitted light from the dark color mark D. The writing mechanism 6 is preferably composed of a printing mechanism such as an inkjet printer.

Next, the operation of the prepaid card reading / writing device 1 with the negative value reading detection function will be described. First, when the prepaid card P is loaded on the reading mechanism 5 at the time of transaction settlement, the reading mechanism 5 reads the latest balance data on the card surface. When the reading is completed, the micro computer 2 operates the negative value detecting means 12. The negative value detecting means 12 operates every time the reading mechanism 5 reads the balance data, and confirms whether or not the balance data read by the reading mechanism 5 is a negative value. This is notified by the alarm 10 and the display device 11 via 2.

[0014]

[Effect of device]

 As described above, the prepaid card read / write device with the negative value read detection function of the present invention is activated each time the read mechanism reads the balance data, and whether the balance data read by the read mechanism is a negative value or not. Since it is configured with a negative value detecting means for confirming whether or not a negative value is detected and notifying the negative value, it is possible to detect an abnormality in the balance read from the prepaid card, thus providing a reliable prepaid card. Since it enables the construction of a system, it has a great effect on the industry.
