Which statement about debit card transactions is accurate?

• A. The funds are moved from the cardholder's account only after the merchant submits the transaction for processing
• B. They are always processed without any fee
• C. They require the cardholder's signature only
• D. They use an electronic funds transfer that happens at payment authorization and generally posts immediately

Answer: (D)

Debit card transactions move funds through an electronic funds transfer right at the moment the payment is authorized. When you present the card, the merchant’s terminal sends an authorization request to your bank, which checks that you have enough funds and, if approved, initiates the transfer and often places a hold on the amount. The actual posting to your account—reflecting the debit—typically happens immediately or within the same day, depending on the network and processor. So describing the transfer as occurring during payment authorization and posting immediately captures how these transactions are generally processed. It’s not accurate to say funds move only after the merchant submits the transaction for settlement, since authorization itself triggers the transfer flow. Also, debit transactions aren’t fee-free, and while PIN is common, signatures are not universal.
