In 1908. the spread of credit unions has reached the United States. In 1935 President Roosevelt signed the state Charter on credit unions, which became a law. Activity of the credit union consists of organizing mutual financial assistance by meeting the needs of its members in the services of saving and obtaining loans. Credit unions of the open type are still controlled by their members, but at the same time provide services to people who are not its members (external customers). The value of credit unions is not limited to the role of the economic agent - they are an important element of the social structure and a factor of social stability and progress. Credit unions, like today's credit unions, emerged in the 19th century in Germany as a result of crop failure and famine. Credit cooperatives and credit unions exist in many different forms. The main differences relate to the nature of the membership and the opening of a credit institution. Unlike banks, in order to use the services of a credit union, you have to become its member, having written an application and having paid thus shares and membership fee. Worldwide credit union movement is represented by regional confederations and national organizations within the World Council of Credit Unions.
