PROBLEM TO BE SOLVED: To improve the convenience related to services of dispensing game media. SOLUTION: CR unit 30 subtracts digital money by an amount more than an amount of a dispensing unit dispensing balls by a single ball-dispensing operation, from digital money stored in an IC tip 110 in a cellular phone 100, and evaluates a negotiable value of the digital money, or the subtraction object, as the negotiable value of a prepaid card so as to, when a player continuously borrows Pachinko balls using the digital money, eliminate an overlapping operation (holding-up operation of the cellular phone 100) of the digital money media.
