When exchanging goods, you need to show the original credit card and your ID card, and get the shopping list. The displayed credit card number should be consistent with the card number on the purchase order. At the same time, it is necessary to register the cardholder's name, credit card number and ID number, which shall be signed by the cardholder for confirmation. Cardholders can purchase 1 full-price movie tickets at preferential prices by swiping the Bank of Communications credit card at the theater ticket window with the value-added movie tickets (see the city list for details on the use of the tickets). Each qualified purchase order can only be exchanged once, and cannot be exchanged repeatedly.
