There is a risk. For this reason, there is a risk that the correct balance processing may be hindered.

The present invention has been made to solve the problems of the prior art, and its purpose is to easily find the recording position of the latest balance data and to easily perform correct balance processing. To provide.

[0007]

[Means for Solving the Problems]

 The prepaid card of the present invention uses a dark mark on either side of "0" or "1" and a light mark on the other side of each bit of the balance data composed of binary numbers, and the card surface On a prepaid card that prints and displays the latest update data every time the balance is updated, and prints the latest update data by adding a row of the dark and light color marks to the old display, a guide pattern is displayed near the printed portion of the latest update data. It is characterized by being printed. Further, the dark color mark may be black and the light color mark may be white. Also. At least one mark of the balance data printed and displayed on the surface of the card is a dark mark. Alternatively, the guide pattern is composed of continuous lines. Alternatively, the guide pattern is constituted by a discontinuous line.

[0008]

[Action]
