Money Transfer

Bank wire transfers are often the most expedient method for transferring funds between bank accounts. A bank wire transfer is effected as follows:
The person wishing to do a transfer (or someone who he has appointed and empowered financially to act on his behalf) goes to the bank and gives the bank the order to transfer a certain amount of money. IBAN and BIC code are given as well so the bank knows where the money needs to be sent to.
The sending bank transmits a message, via a secure system (such as SWIFT or Fedwire), to the receiving bank, requesting that it effect payment according to the instructions given.
The message also includes settlement instructions. The actual transfer is not instantaneous: funds may take several hours or even days to move from the sender's account to the receiver's account.
Either the banks involved must hold a reciprocal account with each other, or the payment must be sent to a bank with such an account, a correspondent bank, for further benefit to the ultimate recip

Short history of online Banking

The precursor for the modern home online banking services were the distance banking services over electronic media from the early '80s. The term online became popular in the late '80s and referred to the use of a terminal, keyboard and TV (or monitor) to access the banking system using a phone line. ‘Home banking’ can also refer to the use of a numeric keypad to send tones down a phone line with instructions to the bank. Online services started in New York in 1981 when four of the city’s major banks (Citibank, Chase Manhattan, Chemical and Manufacturers Hanover) offered home banking services[1] using the videotex system. Because of the commercial failure of videotex these banking services never became popular except in France where the use of videotex (Minitel) was subsidised by the telecom provider and the UK, where the Prestel system was used.
The UK’s first home online banking services[2] was set up by the Nottingham Building Society (NBS) in 1983 ("History of the Nottingham". Retrieved on 2007-12-14.). The system used was based on the UK's Prestel system and used a computer, such as the BBC Micro, or keyboard (Tandata Td1400) connected to the telephone system and television set. The system (known as 'Homelink') allowed on-line viewing of statements, bank transfers and bill payments. In order to make bank transfers and bill payments, a written instruction giving details of the intended recipient had to be sent to the NBS who set the details up on the Homelink system. Typical recipients were gas, electricity and telephone companies and accounts with other banks. Details of payments to be made were input into the NBS system by the account holder via Prestel. A cheque was then sent by NBS to the payee and an advice giving details of the payment was sent to the account holder. BACS was later used to transfer the payment directly.
