In recent decades, many credit unions began to resort to such form of service as National Credit Union Insurance Fund was created by Congress in 1970 to insure deposits of credit union members in the amount of 100 thousand dollars. In the credit union compensation for use of the loan (interest) is a source of compensation for savings. 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.
