Nothing needs to be done.

Many merchants in Hong Kong and Macao have opened UnionPay. When you swipe the card, ask the cashier to go through the UnionPay channel. This way, there is no handling fee. The exchange rate on the day when the card is swiped will be automatically converted into RMB for calculation, and you can pay it back in RMB. , there is no need to apply for anything.

The UnionPay channel is the most convenient, and we don’t charge any fees. If you apply for visa, jcb channel. There is a handling fee.

Except for UnionPay, visa is more convenient than JCB. Visa is the world's largest card issuing organization and can be used in many places around the world. JCB is mainly used in Japan.
