within the definition of "check" in subsection (f) of this section

the effect that the promise or order is not negotiable or is not an

instrument governed by this article.

the instrument may treat it as either.

drawer and drawee are the same bank or branches of the same bank.

countersignature by a person whose specimen signature appears on the

instrument.

acknowledgment by a bank that a sum of money has been received by

the bank and a promise by the bank to repay the sum of money. A

certificate of deposit is a note of the bank.
