什么是 Promissory notes ？

本票（Promissory notes）-由一个人向另一个人作出的无条件书面承诺，由出具人签署，在固定或可确定的未来日期按需向特定人员或持票人，根据其指示支付一定金额。

A promissory note is also a negotiable instrument. It is similar to a draft except that there are only two parties.

PROMISSORY NOTE
“[A]n unconditional promise in writing made by one person to another signed by the maker, engaging to pay, on demand at a fixed or determinable future date a sum certain in money to, or to the order of, a specified person or bearer.” (UK Bills of Exchange Act 1882)

Promissory notes are widely used as debt instruments, for example in long‑term projects containing numerous stage payments, where a buyer or borrower issues one or more promissory notes promising to pay a specified amount on a stated due date.
