A credit union may:
1. Require, at the discretion of the directors, the payment of an entrance fee or annual membership fee of any person admitted to membership;
2. Collect, receive and disburse moneys and charge a fee for services rendered in connection with the sale of negotiable checks, money orders and other money-type instruments and for such other purposes as may provide benefit or convenience to its members; and
3. Assess charges to members in accordance with the bylaws for failure to promptly meet their obligations to the credit union.
