DIAS has developed and is responsible for the operation of DIAS Payment System through which domestic and cross-border interbank payments are cleared and settled. DIAS Payment System includes the following payment schemes: credit transfers, direct debits, card payments, checks, and ATM transactions. Most credit, payment, or electronic money institutions operating in Greece participate in DIAS Payment System. At the same time, its connection to other payment systems operating within the Single European Payments Area (SEPA) provides access to Payment Service Providers within the Euro Area.

DIAS serves as the Greek hub of credit transfers and direct debits. These schemes that are designed in compliance with the specifications set by the second European Payment Services Directive (PSD2) and the Greek Law No 4537/2018, facilitate payments and fund collection procedures. DIAS is overseen directly by the Bank of Greece (BoG) and indirectly by the European Central Bank (ECB). DIAS Payment System also complies with the European Payment Council (EPC) SEPA payment schemes. DIAS offers its services to the Greek Public sector (National Social Security Fund-EFKA, Independent Authority for Public Revenue-IAPR, General Accounting Office, Cadastral Office, municipal water supply and sewerage companies, municipalities, etc.), as well as to the private sector (major electricity and telecommunication companies, insurance companies, companies in the betting industry, etc.).

The Company's Data Center provides a fully-featured, end-to-end solution that any bank or organization can use to access the DIAS Payment System. It is designed on a cutting-edge open architecture method. Hence, it complies with the latest messaging standards and supports multiple communication methods. In the Data Center, suitable and modern infrastructure has been established and solutions of high availability have been adopted, so that the Payment System operates uninterruptedly. In addition, DIAS functional Data Center offers third-party hosting services (Data Center colocation services).

DIAS has significant presence in the field of “account to account” transactions. In this context and in cooperation with Greek commercial banks, it introduced the IRIS Online Payments (for payments via mobile phone/computer) and IRIS e-commerce (for e-shop payments) products.

The Company’s strategy is to develop innovative payment solutions, in cooperation with the financial ecosystem. Its services are addressed to both the public and private sectors in order to contribute to payments modernization and strengthen the national economy.
