Using Credit Cards in China - The Great CC Rip Off (dynamic currency conversion)

This thread aims at helping those using CC's in China to avoid and bust the DCC Scam in China. If you use CC's in China, you may be subject to losing up to 10% of your money each time you use your CC, so please read this thread.

What is it?
DCC stands for Dynamic Currency Conversion. When using some CC's in China, the Chinese bank processing the transaction (whoever's POS/CC machine is used) will automatically convert the transaction into your home currency (country of Bank issuing your CC) and charge that to your bank vs RMB. Thus, your CC bill will indicate the transaction was processed in your home currency vs RMB. The transaction instead should be done in RMB with the Chinese bank charging your bank the RMB amount, then your bank converting to your home currency at a FAIR market rate.

For historical exchange rate data, see this link.

Why is it a "scam"?
First, when many machines detect a foreign CC it automatically selects DCC. Second, DCC receipts indicate you were given a choice to select DCC or opt out when in fact you were not. Third (and most important), with DCC the Chinese bank will give you an unfair rate (typ 4-6% lower than market) when converting to your home currency resulting in a huge loss (gain for them). This occurs at with every foreign CC transaction at every machine that does DCC. The vast majority of foreigners don't know what it is, and for those that do most do not even know how to fight it. Thus, it is a scam.

Lastly, most service people in China do NOT know what DCC is and that the transaction is truly in RMB. When you point out the evidence indicating DCC (see "How can I tell it is happening to me?" below), most service people assume all foreign cards result in that occurring. In fact, many will claim (unknowingly and mistakenly) that they are charging in RMB as indicated on the receipt and your home currency number is only a reference, and also that they cannot select anything else. This is not true.

Where does it occur?
This can occur at almost any machine that accepts CC's in China. However, it is most prevalent at hotels (incl Western chains), some restaurants, and many tourist/souvenir shops. This scam occurs (as reported) only to Visa cards and MC, however it has not yet been reported for Discover, or American Express. It has been reported to mostly occur with Bank of China (BOC) POS machines, though there have been reports with HSBC, China Construction Bank (CCB), and China Bank of Communications (CBC) machines as well.

How can I tell it is happening to me?
It is very easy. There are a few ways:
1. First, on the top of the receipt you might see "DCC" Printed. Not all banks do this though.
2. You will see reference to your local currency and an exchange rate on your receipt. This may be in very small print.
3. You will see text similar to "I declare I have been offered a choice of payment currencies and my choice is final..."

How do I avoid/stop it?
First, refer to these instructions:
DCC Instructions (thanks to jair101)

Then, DO NOT CIRCLE THE RMB AMOUNT. In many other locations such as Europe and Hong Kong when offered a choice you can simply circle the currency of choice. This will not work and you will be charged in your home currency. Instead, ask the transaction to be cancelled and then processed according to the instructions below depending on the processing bank.

1. For Bank of China (BOC) machines or China Construction Bank (CCB) machines, see instructions to print out/save on a smartphone and show to vendor.
2. For HSBC, jamar has provided instructions that appear to finally crack the HSBC scam (only works for chip & pin cards though). Please post your experiences using the instructions in this thread.
3. For Bank of Communications machines, we yet have found a way to stop DCC. Please help us post if you can successfully stop the DCC with Bank of Communications. For now, your best resolution is to call your bank.

HSBC seems to require a code to opt-out or select functions. See tips here and here, and here. Recent reports (as of May 2011) indicate HSBC DCC receipts seem to offer a choice to select currencies. See this example. Please send us/post any experience with these.
