Hong Kong dollar (HKD; symbol HK$) = 100 cents. Notes are in denominations of HK$1,000, 500, 100, 50, 20 and 10. Coins are in denominations of HK$10, 5, 2 and 1, and 50, 20 and 10 cents.
The currency is pegged to the US dollar at a rate of around HK$7.8 to US$1, although this does fluctuate very slightly.
Notes are issued by three banks – HSBC, Standard Chartered Bank and Bank of China – and therefore come in a variety of designs for each denomination; coins, on the other hand are issued by the government.
Hong Kong Dollars are legal tender in Macau (where the currency is the pataca) and can be used on a one-to-one basis. Patacas cannot be used in Hong Kong. Small transactions can also be carried out using value stored on an Octopus card; these are primarily used for public transport, but are now accepted in many shops and vending machines – customers simply touch the card to the reader to the make the transaction.
