What does NSF stand for in relation to checks?

In the context of checks, NSF stands for Non-Sufficient Funds. This term is used when a bank account does not have enough money to cover a check that has been presented for payment. When a check is written and there are insufficient funds in the account to honor that check, the bank may return it as "NSF." This can lead to various consequences, including fees for both the writer of the check and the payee, as the intended transaction is unsuccessful. Recognizing this term is important for understanding banking processes and the implications of writing checks without verifying adequate funds in an account.
