Final answer:
An example of an over-the-counter payment stream automatically concentrated for a payee is online payments made through a payment gateway. This allows for direct electronic transfer of funds, which is more efficient than handling physical checks or cash. A debit card also provides a similar immediate transfer of funds, like a check, while reducing the risks associated with overdrafts.
Step-by-step explanation:
An example of an over-the-counter payment stream that is automatically concentrated for a payee is D) Online payments made through a payment gateway. These types of transactions usually involve the electronic transfer of funds directly from the payer's bank account or credit card to the payee's account, which streamlines the payment process and reduces the need for manual concentration of funds. In contrast, bank transfers initiated by customers, physical checks, and cash payments made at a retail store may require additional steps for the payee to collect and deposit the funds into their account.
A check needs to be deposited by the payee into their bank account to collect the money, and it can take several days for the check to clear, and the funds to be available. On the other hand, a debit card, like a check, is an instruction to the user's bank to transfer money directly and immediately from the bank account to the seller, facilitating an almost instantaneous transaction.
An overdraft occurs when someone withdraws more money from their bank account than is available, leading to a negative balance and potentially incurring fees. This highlights the importance of organized payment streams such as online payments which minimize handling cash or the risk of accidental overdrafts.
