When the credit card is not on the person, you can trade without a card. Cardholders only need to provide the account number, validity period and "last three codes" information of the credit card to realize offline transactions.

This card has been used in online banking, telephone banking or mobile banking. A savings card must be in the same bank as the credit card under its name before the money in the credit card can be transferred out.

It should be noted that after using a credit card, you must repay it on time to avoid overdue, which will affect your personal credit information.
