KB Kookmin Card, the largest financial group in South Korea, has applied for a patent for a stablecoin credit card payment technology. The scheme binds the existing credit card with a blockchain wallet to create a hybrid payment system: during payment, the stablecoin balance in the wallet is used first, and the remaining amount is covered by the credit card. KB stated that this design retains the existing card swiping system, user experience, cashback, and security mechanisms while lowering the threshold for digital asset payments and promoting stablecoins to mainstream finance.
