To provide an admission charging apparatus and an admission charging system for accurately and simply collecting charges.

When entering a game hall, a user operates an operation part 14 of an admission charging apparatus 1, and then pays an admission charge corresponding to the number of persons who want to enter and estimated time of use, to a payment receiving part 15. After the payment, the user acquires admission tickets discharged from a recording part 16 one by one. When leaving the game hall, a manager of the game hall who has received the admission ticket from the user uses a barcode reader part 17 to read a barcode recorded in the admission ticket. On the basis of entry time included in user information indicated by the barcode, exit time specified by using a clock part 12, and so on, a control part 10 calculates an additional charge. When an additional charge is required, the user pays the additional charge in the payment receiving part 15 in the admission charging apparatus 1. Consequently, human errors, money troubles, etc. related to the charging for admission can be reduced.
