| Non-Sufficient Funds (NSF) | In the US banking industry, the term "non-sufficient funds" (NSF) is used to indicate that a demand for payment (a check) cannot be honored because insufficient funds are available in the account on which the instrument was drawn. In simplified terms, a check has been presented for clearance, but the amount written on the check exceeds the available balance in the account. It is often colloquially referred to as a bad check, a "bounced" check, or a returned check. |
