Whether CCB credit cards can be used overseas mainly depends on the card organization’s logo. For example, if you have a UnionPay single-label card, in Birmingham, it can only be used at merchants with the UnionPay logo. Pounds will be directly converted into RMB, free of charge. . However, the coverage of UnionPay in the UK is not as extensive as that of VISA and MASTER, so it is best to get a UnionPay dual-label card with VISA or MASTER to give you an extra range of choices, and it is best to have a global payment function, so no matter which channel you take, They are all converted into RMB with no handling fee, and it is also convenient to repay back home.
