No you cannot. For those that use the normal
service and have a merchant agreement with a South African bank or have a
agreement through which you present the transactions are bound by the
currencies that they support. You will have to present your transactions
in S.A. Rand and you will be settled in Rand. When the transaction
is passed to the cardholders bank for settlement it will be converted to
the cardholders currency during the process. Any change in amount
caused by a variation in the exchange rates will be absorbed by the bank.
