By developing and commercializing the nation’s first-ever bus-subway integrated transportation card system, we have changed the paradigm of public transportation use, and by developing a chip operating system(COS), more than 3 billion people around the world use Kona I’s products in the digital authentication fields such as finance, communication, and public sectors.

Since 2016, Kona I has invested intensively in the platform business, and has built payment platforms, local community platforms, data platforms, and blockchain platforms. Based on these platforms, we’re providing a variety of services such as local currency services, prepaid payment services, delivery services, mobile shopping services, and donation service, etc. The most representative case would be the local currency service based on the local community platform that is an international standard payment service, with an annual transaction amount of 8 trillion won(KRW) and is used by more than 7 million subscribers as of 2020.

Kona I will continue to focus on launching new technologies and services, and aim to become a global platform corporation. We ask for your interests and support for our continuous aspirations and innovation.
