N.J. Stat. § 17:3B-10
If credit under a revolving credit plan is offered and extended in connection with a demand deposit account or other account maintained by the borrower with the lender pursuant to an agreement or arrangement whereby the lender agrees to honor checks, drafts or other debits to the account, which if paid would create or increase a negative balance in the account, by making extensions of credit to the borrower under the revolving credit plan, any charges customarily imposed by the lender, under the terms governing the demand deposit or other transaction account in the absence of any associated revolving credit plan, may continue to be imposed on the account without specific reference thereto or incorporation thereof by reference in the agreement governing the revolving credit plan, and the amount of the charge, to the extent the balance in the demand deposit or other transaction account is insufficient to pay the charge, may be charged to the borrower's account under the plan as a loan thereunder and may be included in outstanding unpaid indebtedness in accordance with the terms of the agreement governing the revolving credit plan.
