Wales uses the same currency as the rest of the United Kingdom, the British Pound Sterling.
Northern Ireland uses the Â£ sterling, the currency in circulation in England, Scotland and Wales. Unlike the Euro which is used in the Republic of Ireland, Â£ sterling is not linked to the Euro. Mastercard (Access) and Visa credit cards are in general use and cheques backed by a bank card are widely accepted.
