Remittances are part of a bank's international services and are divided into two categories, inward and outward. An inward remittance is where a foreign bank sends funds to a domestic bank with an instruction for the bank to pay the funds to the payee. An outward remittance is where a domestic bank sends funds to its' overseas branches, subsidiaries or correspondent banks with an instruction for the receiving bank to pay a certain amount to the nominated payee. Inward and outward remittances are usually carried out by a mail transfer, demand draft （DD）, or telegraphic transfer （TT）. The TT and the DD are the most common methods used. A telegraphic transfer is the quickest and most efficient remittance method available.　汇款是银行国际业务的一部分，它分为两种，汇进和汇出。汇进是指外国银行将资金汇到国内银行并指令该银行付款给收款人的汇款。汇出是指国内银行将资金汇到它的国外分行、子公司或相关银行并指令收款银行付一定金额的款项给指定收款人的汇款。汇进和汇出通常是通过信汇来完成的，即期汇票（DD）或电汇（TT）。TT和DD是用得最多的方法。电汇是最快，也是最高效的汇款方法。
