Kakao Pay's Payment Patent Realizes Seamless Gameplay

Dynamic QR (DQR) is a technology that generates QR codes containing payment information that changes in real time. Unlike the existing Static QR (SQR), which contains fixed information printed at a store, DQR can instantly reflect variable information such as the payment amount.

Kakao Pay used this to build a system that allows customers to complete payment with their smartphone right from their seat, without a separate payment terminal. In particular, it is optimized for the PC bang environment, where gameplay must not be interrupted, and it has received an explosive response from users.

This system provides multifaceted benefits as follows:

• Customer perspective: Immediate payment possible from one's seat, without moving around or facing a clerk
• Development perspective: High reusability and productivity secured by leveraging existing payment networks and APIs
• Business perspective: Reduced cost of introducing separate terminals and rapid scalability toward unmanned stores

Kakao Pay has completed patent registration for this technology in order to prevent competitors from imitating it and to protect its proprietary system architecture and merchant fee-reduction know-how.
