Credit unions attract people in the first place by the opportunity to get cash loan (credit) - quickly and relatively inexpensively. The uniqueness of credit unions is that they put together the principles and benefits of financial cooperatives, consumer cooperatives and mutual aid funds, born once by trade unions. Credit union promotes the effective conservation of personal funds of its members, giving them the loans from the funds of the credit union, as well as the sharing of savings in education, housing, health care and other programs of social support and social development of its members. 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. In some cases, the initiators of credit unions can be trade unions, associations such as social support centers and others. In the UK, credit unions are a source of financing of people groups. This tool is not widely used.
