Historically, credit unions were preceded by widespread development of credit cooperation in many countries of Europe and America. First Credit Union was savings unprofitable institution, or rather credit cooperative, providing services to its members. Typically new members of the credit union become citizens having suretyship or recommendations from their friends - members of the credit union. Cooperation between credit unions, how they would not have been named, took place always, from the moment when the movement moved outside one credit union. The main advantage of credit unions consists in transparency, controllability, governance for shareholders. A potential new member of a credit union must submit a recommendation of shareholders in which the referee becomes a warrant of a future member of the credit union. The relationship between credit unions and shareholders arise from the membership and are not customer relationship. In some cases, the initiators of credit unions can be trade unions, associations such as social support centers and others. The right to use the services of the credit union have only its members. 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.
