KB Kookmin Card Patents Hybrid Blockchain Wallet and Credit Card Payment System
According to KB Financial Group, the patented system enables stablecoin transactions through linked credit cards, automatically covering shortfalls to ease digital asset adoption in everyday payments.
Fact Check
The assessment is "likely_true" with high confidence based on strong and consistent evidence from multiple relevant sources. Three independent sources, including the highly authoritative publication The Block, corroborate the central claim that KB Kookmin Card has initiated the patent process for a system that integrates a blockchain-based digital wallet with a credit card. The sources consistently describe this as a "hybrid digital asset payment technology."There is, however, a minor but important semantic discrepancy. The statement claims the company "obtained" a patent, which implies the patent was officially granted. The provided sources uniformly state that the company "filed" a patent application. Filing is the initial step in a potentially long process that does not guarantee the patent will be granted. Despite this inaccuracy regarding the status of the patent, the core elements of the statement—the entity (KB Kookmin Card), the action (seeking a patent), and the technology (hybrid blockchain/credit card system)—are strongly supported. The evidence confirms the company is officially pursuing this patent, making the statement substantially true. The irrelevant and low-authority sources were disregarded in this analysis.

The technology deducts payments from the stablecoin balance first, and if insufficient, covers the remainder using the linked credit card.
