Hereinafter, the account information will be described below.

A bankbook refers to a book that records the deposit and withdrawal of a deposit or loan in a financial institution. The bankbook may provide information such as a deposit and withdrawal history and a balance of an account corresponding to the bankbook. However, in the current financial affairs, such a bank account is rapidly replaced by cards such as cash or credit cards and Internet banking. That is, most people use banking services such as account checking through a card or internet banking.

Figure 1a is a view showing an account inquiry method using a conventional cash dispenser, Figure 1b is a view showing an account inquiry method using a conventional Internet banking.
