Negotiable order of withdrawal account
In the United States, a negotiable order of withdrawal account (NOW account) is an interest-paying deposit account on which an unlimited number of checks may be written. A negotiable order of withdrawal is essentially identical to a check drawn on a demand deposit account, but US banking regulations define the terms "demand deposit account" and "negotiable order of withdrawal account" separately.
