Accredited certification (yessign) is a service that issues and manages accredited certificates used for confirming transaction parties in electronic transactions and for preventing e-document fraud.
yessign certificates are issued by financial institutions free-of-charge and can be used for Internet banking and credit card payments to online shopping malls.
In 2008, KFTC started to provide the Virtual Machine (VM) banking service which enables secure electronic signature using wireless devices and to issue security server certificates needed for encoding personal information.

The Korea Financial Information Sharing and Analysis Center(KF-ISAC) was established to effectively detect, prevent and/or respond to attacks on major information and communications infrastructure of financial institutions. The center's major task is to collect and analyze all-encompassing information about the sector, then forward pertinent information to the financial sector to effectively detect, prevent and/or react to hacking, computer viruses and cyber terrorism attempts. KF-ISAC was established within KFTC under the Law of Critical Infrastructure Protection in December 2002. Since its official launch, the center has been providing real-time, around-the-clock services.

Housing subscription savings and deposit schemes, which were available only from Korea Housing Bank (currently Kookmin Bank), were expanded to financial institutions designated by the Construction and Transportation Minister (currently the Minister of Land, Transport and Maritime Affairs) in March 2000. With the expansion came the need to manage the joint businesses of banks related to housing subscription. Accordingly, the ministry designated KFTC as the electronic housing subscription management institution.
KFTC supervises housing subscription accounts to prevent multiple openings of housing saving accounts and manages subscription and benefiters of the housing lottery.
