Hello! I would like to ask you, in Haitao, amazon.com, do you need to open online banking or overseas payment function after opening CCB's dual-currency credit card?
you don't need to directly record the three digits on the back of the card number's validity period as long as the word MASTER or VISA is on the card. The Bank of Communications I use will make a phone call to confirm it when shopping overseas for the first time, and I don't know whether CCB has this service or not. Be careful not to be scared.
