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.
