Bank of Korea and Samsung Team Up for Offline CBDC Research
In a move aimed at advancing central bank digital currency (CBDC) technology, the Bank of Korea (BOK) signed a memorandum of understanding (MoU) with Samsung Electronics on Monday, according to a press release. The agreement was sealed during a signing ceremony attended by Lee Seung-heon, BOK’s Senior Deputy Governor, and Choi Won-joon, Executive Vice President and Head of Development in the Mobile Experience (MX) Division at Samsung Electronics.
Under the terms of the MoU, both parties have committed to ongoing research on CBDC issued by the Bank of Korea, with a specific focus on collaboration in the offline payment sector. Samsung Electronics had previously participated in the second phase of the CBDC simulation study conducted by the BOK last year.

CBDC without Internet
The company’s efforts have led to the development of an offline CBDC technology that facilitates transfers and payments via near-field communication (NFC) between devices without requiring an internet connection. These transactions are conducted within the embedded secure element (eSE) chip of Samsung Electronics’ mobile devices, which holds one of the highest levels of security certification, CC EAL 6+.
The Evaluation Assurance Level (EAL) is a numeric grading system that measures the security level of tech products and systems according to the Common Criteria (CC) security standard. It ranges from EAL0 to EAL7, with EAL7 representing the highest level of security.
Leveraging this technology, the BOK and Samsung will continue their joint research to enhance security in offline payments using Samsung Galaxy smartphones and watches. Additionally, they aim to provide support for stable payments in situations where network connectivity is disrupted, such as during disasters.
Growing interest in CBDCs
Given the global interest in CBDCs, with central banks worldwide exploring their potential, the research collaboration between the BOK and Samsung assumes great significance. The results of this partnership will guide further cooperative efforts to develop the international CBDC ecosystem.
BOK Senior Deputy Governor Lee Seung-heon emphasized the significance of the joint achievement, expressing optimism that the partnership would keep Korea at the forefront of offline CBDC technology.
Samsung’s Executive Vice President Choi Won-joon underscored that the company’s collaboration with the Korean central bank allowed Samsung to utilize its advanced security technology in digital currency. He expected their combined efforts would considerably contribute to the global development of CBDC technology.
