煩わしくなる。There is also a method in which a magnetic card is used in place of the wireless card and data such as a balance is printed on the surface of the magnetic card. In the case of this method, the data such as the balance printed once is not erased thereafter, so that the reliability of the data display is high. However, in the magnetic card itself, data is input by a contact method. Therefore, each time data is input, the magnetic card must be passed to a specific place, which makes it difficult to take the magnetic card in and out.

Has a built-in antenna 12 for receiving a signal from the outside. When the wireless card 11 is used for a prepaid system ticket, for example, data such as a boarding fee is received by the antenna 12. The data received by the antenna 12 is sent to the signal processing unit 13. The signal processing unit 13 is configured by a microcomputer or the like, for example, the wireless card 11
The difference between the amount paid for the purchase and the boarding fare, so-called balance, etc. is calculated. The result of this calculation is written as data in the memory 14 and simultaneously added to the controller 15. The controller 15 has a plurality of output terminals 151-155. The output terminals 151 to 155 correspond to the amount of the balance, for example. For example, the output terminal 151 has a balance of 25
The output terminal 155 corresponds to the balance of 500 yen, and the output terminal 155 is set to have a width of, for example, 500 yen. Therefore, if the balance is 2500 yen, the output terminal 151
In addition, when the balance is 500 yen, a signal is output to the output terminal 155. Further, heaters H1 to H5 are connected to the output terminals 151 to 155, respectively.
5 are arranged parallel to each other in the wireless card. The other ends of the heaters H1 to H5 are connected to the power supply 16. Then, for example, when a signal is output to the output terminal 151, a current flows through the heater H1 to generate heat. In addition, each heater H
A thermal paper (not shown) is arranged above the area where 1 to H5 are arranged, and this thermal paper is formed on the surface of the wireless card, for example, so that the condition of the thermal paper can be observed from the outside of the wireless card 11. Has become. Therefore, for example, when a current flows through the heater H1, the heat discolors the thermal paper located near the heater H1.

で、残金表示の信頼性が高まる。The relationship between the heater and the thermal paper will be described with reference to FIG. Reference numeral 21 denotes a mount, which forms the bottom of the wireless card, for example. A heater H is located above the mount 21, and the heater H is connected to the power supply 22. Also,
Reference numeral 23 is a thermal paper. Therefore, when an electric current flows through the heater H, the heat-sensitive paper 23 above it is discolored. It should be noted that the heater H through which the current flows is selected according to the remaining money displayed by the control of the controller 15. For example, FIG. 3 shows a wireless card 3.
In the figure showing the surface of No. 1, for example, 2500 yen, 2000
The balances M1 to M5 are displayed like circles, and a heater (not shown) is arranged corresponding to the display. And
First, N1 is discolored near the remaining balance display of 2500 yen, and then N2 is discolored near the remaining balance display of 2500 yen. In this way, the discolored area gradually moves to the one with less remaining money. It should be noted that when the thermal paper changes color, the color change state remains after that, so it is not necessary to continuously apply heat to the heater. Further, even if the battery runs out or the wireless card is destroyed, it remains as a record, so that the reliability of the balance display is improved.

However, the number of remaining money, the number of output terminals corresponding to the remaining money, the number of heaters, and the like are appropriately set depending on the remaining money to be displayed. Further, in the above-described embodiment, the example of the balance display is explained, but the present invention is not limited to the balance display and can be used for displaying other data.
