To activate the overseas online cardless payment function, most overseas consumption must activate this function. It is a high-risk industry. Call 95588 to activate it before the transaction, and call to close it after completion. Your card can be used in a foreign currency account. To make a payment, exchange US dollars for Hong Kong dollars based on the exchange rate on the day of accounting. This is equivalent to the transaction being made in Hong Kong dollars and the deduction being made in US dollars~
