Some may know that in China people use dual currency cards, and the MC/Visa part is usually USD or EUR. If you charge anything other than your card's foreign denomination to your card's MC/Visa part, the conversion is subjected to 1% or 1.5% conversion charge.

Now if you apply for a high-end card in China, you don't pay this 1% or 1.5% when say. If you are charge AUD through MC/Visa tunnel on a RMB/USD dual currency card, it is converted to USD without a fee, and billed to your card in USD. At the end of the billing cycle, you pay it back with RMB, using the bank's USD to RMB exchange rate.

However, ICBC introduced a card that has 10 currencies. If you are charged these 10, the charge is billed using those currencies. Now you have a RMB/USD/EUR/AUD/xxx card. Using the last example of charging AUD to the card, there is no conversion from AUD to USD. You pay the AUD charge at the end of billing cycle with RMB, using the bank's rate of AUD to RMB.

I don't have that card, but I kept wondering, does that mean you can go to the countries using these 10 currencies, and act like you have a native card there? Therefore you cannot be hit by DCC in those countries?

Like you go to USA, the machines think you use a USD card. Then you go to Europe, the machines in Europe think you use a EUR card. There is no way to be DCCed if things are like this, right?
