Membership in the credit union is voluntary and is open to all citizens bound by with joint work or residence, who wished to create a credit union to use its services and are willing to take on relevant commitments and responsibilities. Credit unions attract people in the first place by the opportunity to get cash loan (credit) - quickly and relatively inexpensively. The main advantage of credit unions consists in transparency, controllability, governance for shareholders. Credit unions are competitors of savings institutions, adding interest on deposits of members. This applies to the shares, as well as to additional funds transferred to the account in the credit union. Credit unions are financial institutions, financial cooperatives of citizens, and in this capacity they are above all associations of people, not unification of capitals, which is typical, for example, for public companies. Credit unions encourage the proper use of shareholders savings, developing social programs (education, health, recreation, housing, etc.).
