KakaoPay was cited by the Financial Supervisory Service for providing the personal credit information of 40.45 million users to China's Alipay without consent. The transferred data included account identifiers, contact details, sign-up information and transaction histories, while KakaoPay countered that it was a lawful outsourcing of business operations. A request for materials from the Personal Information Protection Commission and a police investigation followed, and a court ruled that a fine of about 6 billion won was justified.
