Description
PortOne Solutions, formerly known as Chai Corporation, operated the CHAI payment service in South Korea, which launched in 2019. The service included "CHAI Simple Payment" for online use and a physical "CHAI Check Card" for online and offline transactions, funded by a prepaid digital wallet called "CHAI Money". Due to changes in the investment environment and economic downturns, the company has ceased its B2C operations to focus on B2B services. The shutdown has been phased, with new sign-ups ending in September 2024, payment services terminating in November 2024, and the CHAI app being fully discontinued in April 2025. The company is currently facilitating refunds for remaining user balances.
