The process of setting accounts or debts between parties
   residing at a distance from each other, without the intervention of
   money, by exchanging orders or drafts, called bills of exchange. These
   may be drawn in one country and payable in another, in which case they
   are called foreign bills; or they may be drawn and made payable in the
   same country, in which case they are called inland bills. The term bill
   of exchange is often abbreviated into exchange; as, to buy or sell
   exchange.
