Although the dual-currency card does not support VbV of VISA and SecureCode of MatserCard for online verification, it has the advantage over Great Wall International Card in that it supports DCC ("Dynamic Currency Conversion") transactions, and it can be swiped/cashed overseas through UnionPay network. Bank of China series dual-currency credit cards can also be spent on foreign websites, as long as the websites provide non-VbV or SecureCode authentication methods.
