英文名称：Bill of Exchange 中文名称：汇票
出票人签发，委托付款人在见票时或者在指定日期无条件支付确定的金额给收款人或者持票人的票据。

A non-interest-bearing written order used primarily in international trade that binds one party to pay a fixed sum of money to another party at a predetermined future date. 

Bills of exchange are similar to checks and promissory notes. They can be drawn by individuals or banks and are generally transferable by endorsements. The difference between a promissory note and a bill of exchange is that this product is transferable and can bind one party to pay a third party that was not involved in its creation. If these bills are issued by a bank, they can be referred to as bank drafts. If they are issued by individuals, they can be referred to as trade drafts.
