To date, credit unions - virtually the only form of financial institution where people can quickly and without any problems get a relatively inexpensive cash loan. Credit unions attract people in the first place by the opportunity to get cash loan (credit) - quickly and relatively inexpensively. In the credit union compensation for use of the loan (interest) is a source of compensation for savings. Credit unions historically formed as a special form of social support, initially taken upon themselves the social mission of protecting the interests of citizens in the field of financial services. Unlike banks credit unions limit their activities to a closed circle of people.
