The pataca is Macao's official currency, divided into 100 avos. The Tourism Office uses the code MOP in its practical information. A guide should retain that currency even when a visitor also encounters Hong Kong-dollar prices or an international bookmaker displays a different account currency. [2]

An MOP bank balance, a stored-value card and a foreign-currency online account each record money separately. Before comparing payment costs, identify which of those balances is being charged and which will receive a refund or withdrawal. Keep the original MOP amount as the reference point so that a conversion does not disappear inside a larger-looking balance.
