This bill mandates the acceptance of cash as a payment method for certain retail transactions and public fees in South Dakota. Specifically, it requires that cash be accepted for goods or services sold in person, where the seller or their employee is present, the purchaser opts to pay with cash, and the transaction amount is $100 or less. Additionally, sellers are prohibited from charging higher prices for cash payments. The bill defines "cash" as physical coin, currency, or notes recognized as legal tender by federal law.

However, the bill outlines exceptions where these cash acceptance requirements do not apply, including transactions involving federally chartered credit unions, financial institutions, sales requiring credit cards for security deposits, and payments made on airplanes. Furthermore, it stipulates that state and local governments must also accept cash for fees or charges under the same conditions, ensuring that no additional fees are imposed for cash transactions.
