(b) A Basic Checking Account shall be established by either (1) a minimum initial deposit of $100, or (2) a written agreement with the account holder requiring direct deposits with the financial institution by a third party of recurring payments due to the account holder on at least a monthly basis. Except as provided in subsection (d) of this Section, no other minimum balance or minimum deposit requirement may be imposed on a Basic Checking Account. (c) No activity charge may be imposed for the first 10 checks drawn on a Basic Checking Account in any calendar month, provided that a financial institution may charge its customary fee for a stop payment order or any transaction resulting in a check returned due to insufficient funds. (d) A financial institution may offer any person 65 years of age or older a consumer-deposit account with terms that are more favorable to such person than the terms required under this Section and may designate such an account as a Basic Checking Account.
