PROBLEM TO BE SOLVED: To precisely predict the occurrence of shortage in the balance of an account and to warn a user.SOLUTION: An account balance specification unit 111 of an account management server 10 specifies the account balance of an account of a user who uses a communication terminal 20. A first withdrawal prediction specification unit 114 specifies a first withdrawal prediction amount, an amount expected to be withdrawn from the account, on the basis of information on future behavior of the user. A determination unit 115 determines whether shortage in the account balance occurs or not by comparing the account balance with the first withdrawal prediction amount. A display control unit 116 causes a display unit 24 of the communication terminal 20 to display a warning to the user, if shortage in the account balance occurs.SELECTED DRAWING: Figure 2
