Credit unions attract people in the first place by the opportunity to get cash loan (credit) - quickly and relatively inexpensively. Principles of cooperative democracy and interaction were adequate to the purposes for which people joined credit unions. At the organization of the credit union it is important that people know each other and know the extent to which each of them is trustworthy. Taking a decision to join a credit union, citizens create an organization through which they participate in the shared savings by mutual crediting and joint (collective) use of personal savings. 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. On the consumer credit market in the U.S. credit unions are on the third place after the commercial banks and finance companies and are ahead of savings institutions, not taking into account the loans on real estate. Credit union as a consumer cooperative operates on the principles of equality of all its members.
