The manual contains use cases, descriptions of functions and format of data. ### About the Service The Documents Service receives digital documents and forwards them to RB (Reiknistofa bankanna), for publication in all online banks. The documents can be of various forms such as payrolls, passwords, payment slips, statements and accounts. The service is useful for customers who want to submit electronic documents directly from their accounting or payroll systems. ### RB - Displayment System (Birtingakerfi RB) Reiknistofa bankanna (RB) has a centralized publication system, Birtingur, which all online banks of Iceland connect to. Electronic documents submitted are therefore accessible to the recipient irrespective of the financial institution with which the sender of the document is part of. ### Identity and Access Management Access control for the service follows the same model as the Arion online banking system, where users are authenticated with a username and password. Additionally, communications between the web service and the user’s system are signed with an electronic certificate. The Documents Service is built on a schema interface that all the major banks in Iceland came to an agreement on. The service has a defined WCF endpoint with a Mutual Authentication security model. Information transmitted between systems is encrypted over HTTPS, ensuring maximum security. For detailed instructions on authentication for B2B services, refer to the manual - [Authentication and Certificates](/b2b-2013-schema/b2b-services/b2b-setting-up-a-authentication-and-certificates.md). ### Web Paths The Documents Service is available at the following URL: ### Schema Schema descriptions, including WSDL files, are available at the following URL:
