The difference between credit unions and banks is clearly is apparent when comparing the structure of assets and liabilities of credit unions and banks. Share contributions are transferred to the credit union on the basis of membership for the whole stay of a shareholder as member of the credit union and are the basis of membership. Income derived from the provision of services to its members, does not become the profit of credit union and is distributed among its members in proportion to their savings. 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. 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.
