PROBLEM TO BE SOLVED: To allow payment processing again using a payment ticket, until the payment processing is completed, even when the payment ticket has been read once by a payment device.SOLUTION: A payment system 100 includes: scanning stations 10 for registering articles; and payment stations 20 for carrying out payment processing of a charge of the registered articles. The payment station 20 determines whether it has an authority to carry out a transaction of a payment ticket. When carrying out payment by using the payment ticket of which a transaction code 51 has been scanned but the payment has not yet been completed, an own authority of the corresponding payment station 20 is validated after invalidating the authority of the payment station 20 which has scanned the transaction code 51. |
