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. (Investopedia)

bill of exchange A written, unconditional order by one party (the drawer) to another (the drawee) to pay a certain sum, either immediately (a sight bill) or on a fixed date (a term bill), for payment of goods and/or services received. (BusinessDictionary.com)
