After swiping CCB Platinum Credit Card in Singapore, the available amount prompted by SMS will be deducted according to the US dollar exchange rate.
The available amount, as well as the dollar amount displayed in the text message at that time, can only be used as a reference, and the actual amount can only be determined after the transaction is recorded. When using CCB's platinum credit card to trade in Singapore, the transaction currency will eventually be converted into RMB, and there is no exchange rate difference and no exchange fee.
