A. The following apply to closed end loans, other than closed end loans subject to title 6, chapter 5, in which the principal amount of the loan does not exceed five thousand dollars:

1. 1. Interest not to exceed the maximum rate set by contract may be charged. Interest may be computed either at the single annual percentage rate using the actuarial method or it may be precomputed on the assumption that all payments will be made in the amounts and on the dates scheduled and added to the principal of the loan. If interest is precomputed, the fact that payments are made either before or after the date due does not affect the amount of interest which the lender may charge or receive. If such precomputed interest loan balance is prepaid in full by cash, a new loan, refinancing or otherwise, the lender or holder shall charge only for interest which has been earned and unpaid late or delinquency charges as of the date of prepayment, and the borrower shall receive a rebate of that portion of the precomputed interest which is the difference between the total precomputed interest charges and the charges at the contract interest rate computed on the unpaid principal balance based on the number of days or months to maturity based on either a thirty-day month-three hundred sixty day year or daily three hundred sixty-five or three hundred sixty-six day year on the number of days remaining to final maturity. The amount of such rebate shall not be computed pursuant to the method commonly known as the "rule of 78's". To simplify the calculation of earned interest, it is permissible to assume that all payments were made as originally scheduled or as otherwise mutually agreed.
2. 2. It is permissible to calculate interest on an annual basis of twelve months of thirty days each, or on a daily basis if a day is counted either as 1/360th, 1/365th, or 1/366th of a year, as the lender and borrower may agree by writing. The lender may also charge a late payment or delinquency charge, in addition to all interest charges permitted, on each installment not paid in full within ten days of its due date in an amount not to exceed five per cent of the installment or ten dollars, whichever is less.

C. Except as provided in subsection D of this section a credit card revolving account, including an account that permits access by check, is governed by the laws of this state and is subject to this subsection. Under a credit card revolving account, which the borrower may pay at any time but has the privilege of paying in installments, interest not to exceed the maximum rate set by contract may be charged on the unpaid balances of the account, calculated as of the regular monthly billing date or on the actual or average daily balances outstanding. If the contract provides, the issuer or holder of a credit card revolving account may charge and collect as interest and include in the balances of the account, in addition to or in lieu of interest on the unpaid balances of the account, any of the following:

1. 1. An annual or other periodic charge.
2. 2. A transaction charge for each separate purchase or loan.
3. 3. A minimum interest charge for each regular billing date on which interest charges are due on the unpaid balances.
4. 4. A late payment or delinquency charge.
5. 5. A returned payment charge.
6. 6. A stop payment charge.
7. 7. An overlimit charge.
8. 8. A charge for providing invoices, checks or documentary evidence.
9. 9. A fee incident to the application for and the opening and administration of the credit card account.

10. 10. An automated teller machine or similar electronic or interchange fee or charge.

    If a credit card issuer makes a loan to a borrower by purchasing or satisfying an obligation of the borrower pursuant to the use of a lender credit card or similar arrangement and the purchase or satisfaction is made at less than the face amount of the obligation, the discount is not considered interest.
