About Telex Technology
The telex network are used to send text-based messages. It is a switched network of teleprinters, similar to a telephone network. It is used as early as 1926 and gained widespread use after 1945. The Telex technology is similar to modern day fax, email and texting though is less used but still relevant in selected industry such as the maritime industry.
The 1977 SWIFT messaging services:
- Message Platform
- Computer system to validate & route messages
- A set of message standards
The standards were developed to allow a common understanding of the data, across different languages and banking systems. This will allow seamless and automated receiving and processing of communication exchanged between banks (users).
The Standards
The standards are defined under ISO 9362 – a standard format of Business Identifier Codes which is known as SWIFT-BIC, BIC code, SWIFT ID or SWIFT code. The ISO 9362 is approved by the International Organization for Standardization (ISO)
ISO, the International Organization for Standardization develop and publish International Standards. The standards give world-class specifications for products, services and systems, to ensure quality, safety and efficiency. They are instrumental in facilitating international trade.
