Self-payment system, management apparatus, and terminal management method

A self-payment system comprising a product registration terminal that registers a product to be purchased, a payment terminal with which a customer makes payment, and a management apparatus that manages the product registration terminal and the payment terminal, wherein

• the payment terminal includes
• a money-insertion acceptor for accepting insertion of cash upon payment for a product to be purchased that has been registered on a basis of the product registration terminal, and
• a money-ejection acceptor for accepting ejection of cash on the basis of a manipulation performed by a customer on the payment terminal,
• the management apparatus includes a processor configured
• to determines an amount of cash within the payment terminal, to restrict money-insertion acceptance by the money-insertion acceptor of the payment terminal or money-ejection acceptance by the money-ejection acceptor of the payment terminal in accordance with the amount of cash determined by the processor, and
• to count, by means of a management counter, the sum of a number from a start of product registration by the product registration terminal to an end of payment by the payment terminal and a number from a start of money-ejection acceptance by the payment terminal to an end of money ejection, wherein
• when a ratio of a value of the management counter counted by the processor to a total number of payment terminals is equal to or greater than a third threshold, the processor limits a number of payment terminals with the money-ejection acceptor accepting money ejection.
