And the data code structure of the data code of the value information initially set to be held by the prepaid card and the data code of the value information in the process of using the prepaid card described above. It is characterized by having the same digit recording area for each digit.

Further, in the prepaid card according to the present invention, the coded value information is information indicating at least the amount of money coded by a one-dimensional or two-dimensional recording code, and the first set value information is At least the information indicating the initially set amount is written, and the value information of the process of using the prepaid card includes at least information indicating the remaining amount of the process of using the prepaid card.

[0010]

[Action]

 The prepaid card of the present invention has the same digit recording area for each digit of each value code of the value code initially set by the prepaid card and the data code of the value information in the process of using the prepaid card. Since it is provided over the front of N prepaid cards, information indicating the amount of money coded by the data recording code written in the value information code area when a tampering such as disconnection and connection of the prepaid card is performed. The data code of the value information indicating the balance and the balance is destroyed, making this information meaningless and effectively preventing fraud such as modification.

In the prepaid card according to the present invention, at least the initially set amount of money is used as an initial code in which information encoded by a one-dimensional or two-dimensional recording code is written, and the prepaid card is used. Since the balance code in which the information coded by the one-dimensional or two-dimensional recording code indicating at least the balance of the process is written is divided into N pieces of the same digit recording area and distributed over the entire surface of the prepaid card, If the prepaid card is disconnected or remodeled to make a fraud, the information on the initial code or the balance code will be destroyed, and the information will be meaningless to prevent the fraud such as remodeling effectively.
