Overseas, the same merchant may have multiple acceptance networks, so when shopping by credit card, it is best to remind merchants that they want to settle accounts through the "UnionPay" network.
Merchants with the "UnionPay" logo will use local currency (such as Hong Kong dollars or Singapore dollars) when swiping their cards overseas. China UnionPay automatically converts the currency according to the foreign exchange quotation published by domestic banks on the day of the transaction, and then directly deducts the RMB funds on the card without going through any foreign exchange purchase procedures or paying any handling fees.
