The card processing unit 8 notifies the control unit 2 of the transaction authentication result (s16), and ends this processing. Further, the card processing unit 8 uses the encryption function unit 30b to convert the card data read from the credit card 20 in s13, the authentication code input in s14, the transaction data including the current transaction amount, and the like, as necessary. Encrypt and send this encrypted transaction data to the authentication center. The control unit 30 outputs the encrypted transaction data to the control unit 2 in the same manner as the transaction authentication request described above. The control unit 2 controls the communication unit 10 and transmits the transaction data notified from the card processing unit 8 to the authentication center.

If the transaction authentication result is tradeable, the ticket vending machine 1 discharges the credit card 20 received by the card processing unit 8 in s11 to the card insertion / discharge port 8a, and the ticket issuing unit 5 receives the ticket in s1. The ticketing process of discharging the ticket according to the information to the ticketing port 5a is performed (s4, s5), and the process returns to s1. On the other hand, if the transaction authentication result is non-transaction, the ticket vending machine 1 releases the credit card 20 received by the card processing unit 8 at s11 to the card insertion / discharge port 8a (s4, s6) and returns to s1. In s6, the ticketing unit 5 does not issue a ticket according to the ticket information received in s1.

Further, when the control unit 2 determines in s2 that the payment is made by money instead of credit card payment, the coin processing unit 6 accepts the coins to be inserted by the user, and the bill processing unit 7 accepts the coins to be inserted by the user. Accept. The control unit 2 waits for the total amount of money inserted in the coin insertion slot 6a and the bill insertion slot 7a to be equal to or greater than the transaction amount of the ticket according to the ticket information received in s1 (s7). When the total amount of money inserted in the coin slot 6a and the bill slot 7a exceeds the transaction amount of the ticket according to the ticket information received in s1, the control unit 2 of the ticket issued this time Settle the transaction amount in cash (s8). When the ticket vending machine 1 settles the transaction amount for issuing the ticket in cash, the coin processing unit 6 and the bill processing unit 7 release change as necessary, and the ticket issuing unit 5 accepts the ticket this time. The ticketing process of discharging the ticket according to the information to the ticketing port 5a is performed (s9), and the process returns to s1.

The ticket vending machine 1 may shift to the processing after s7 when the transaction amount for issuing the ticket cannot be settled by the credit card. Further, the control unit 30 determines whether or not the credit card received in s11 is within the expiration date before accepting the input of the authentication code, and if the credit card is not within the expiration date, the control unit 30 accepts the input of the authentication code. It may be configured without.
