A method of counting currency documents including a plurality of coded data portions thereon. Each coded data portion is indicative of an identity of the currency document and the method includes, sensing at least one coded data portion for each currency document using a sensing device. This is used to generate indicating data, which is transferred to a computer system, to allow the computer system to determine the identity for each currency document. The identity is then used to determine a value for each currency document, allowing the documents to be counted.
