Swift is a provider of secure message platform for financial institutions mainly for banks.
Swift messages are being sent and received by banks in encrypted forms. As a result swift messages are accepted as a valid and reliable way of communication between banks.
For example, an issuing bank sends a swift message to an advising bank in order to inform issuance of a documentary credit. Similarly the advising bank sends its acknowledgement via a swift message.
Swift messages play a key role not only in letters of credit but also other payment methods in international trade such as cash in advance payment, documentary collections, open accounts and bank payment obligations.
