South Korean financial giant KB Company applies for stablecoin credit card patent

According to The Block, KB Kookmin Card, a subsidiary of South Korea's largest financial group KB Financial, has submitted a patent application for stablecoin payment technology.

The patent covers a hybrid payment system that allows users to pay with stablecoins through existing credit cards. According to the design, users can link their blockchain wallet address to their existing credit card, and during payment, the stablecoin balance in the linked e-wallet will be deducted first; if the balance is insufficient, the remaining amount will be charged to the credit card. KB stated that this design aims to retain the existing card payment infrastructure, familiar user experience, and related benefits (such as rewards and protections), while lowering the barriers to digital asset payments, helping stablecoins transition from niche platforms to mainstream finance.
