ISO 4217 instead of translated currency names or ambiguous currency symbols. ISO 4217 codes are used on airline tickets and international train tickets to remove any ambiguity about the price. The first two letters of the code are the two letters of the ISO 3166-1 alpha-2 country codes (which are also used as the basis for national top-level domains on the Internet) and the third is usually the initial of the currency itself. So Japan's currency code is JPY—JP for Japan and Y for yen. This eliminates the problem caused by the names "dollar, franc, peso" and "pound" being used in dozens
ISO/TC 37 are closely linked to the standardization efforts of IEC (International Electrotechnical Commission, founded in 1906) and ISO (International Organization for Standardization, founded in 1946). A terminology standard according to ISO/IEC Guide 2 (1996) is defined as "standard that is concerned with terms, usually accompanied by their definitions, and sometimes by explanatory notes, illustrations, examples, etc." ISO 1087-1:2000 defines terminology as ""set of designations belonging to one special language" and designations as "representation of a concept by a sign which denotes it"." Here, concept representation goes beyond terms (being only linguistic signs), which is also supported by the state-of-the-art of terminology
