I received my Bank of America Platinum Check Card before I came to Chengdu. There is a Visa logo on it. It means, I can access my money I deposited in U.S. at all ATM machines here. To check whether it works, I checked the balance with China Construction Bank ATM. It shows the money in currency of Renminbi (RMB). Also, I successfully withdraw 100 RMB from the ATM. I checked the balance again. Only 100 RMB was deducted from the account. It seemed to me that there are no service charge for withdraw cash here, even though I used it on ATM of another bank (and another country).
I was able to check the balance of the card in ATM in Chengdu also. I didn’t try to withdraw money this time.
