PURPOSE:To prevent the deterioration in a service to a customer by providing a means for arbitrarily setting and changing the corresponding relation of a POS processing and a card reader/writer. CONSTITUTION:POS processing machines 11-1n and the card reader/writers 21-2n are separated and the plural sets thereof are disposed. Further, the respective POS processing machines 11-1n and the respective card reader/ writers 21-2n are communicably connected through a communication line 3 and the corresponding relation therebetween can be arbitrarily set and changed. Accordingly, even if the linked card reader/writer is troubled, other card reader/writer can be used. Thereby, a payment processing unable by the card can be prevented. |
