Payment expertise.
Built in real operations since 2014.

From express checkout to financial institutions’ PG systems and commerce payment and settlement.
We have built and operated it ourselves and have added depth to our payment technology.

Technology to create a system.
Founded in 2013, we began express checkout development and PG consulting in 2014. Our experience grew through KB Kookmin Card, overseas PG systems, and payment and prepaid systems for Kurly and Ohouse.

Experience supporting ongoing operations.
After implementation, we support PG modernization, new payment integrations and settlement maintenance. Operational experience informs the next system we build.
