Although the pataca is the legal tender of Macau, the Hong Kong dollar is almost universally acceptable in the Region, and in some cases, is preferred to the Pataca. Circulation of the pataca is mandated by a decree (Decreto-Lei n.º 16/95/M) prohibiting refusal by merchants, but some casinos flout this rule and refuse bets in patacas. The Hong Kong dollar and Chinese yuan are generally accepted throughout Macau from casinos to restaurants. Payments to government agencies can also be made in both Hong Kong dollars and patacas.
