Japan Korea Stablecoin: Will AI Checks Transform Tourist Payments? Two business groups on opposite sides of the sea have taken a new step. On 13 October, South Korea’s KB Kookmin Card said it
Two business groups on opposite sides of the sea have taken a new step. On 13 October, South Korea’s KB Kookmin Card said it signed a cooperation agreement with Japan’s SBI Holdings, a Korean security firm and a joint company to test identity checks for AI agents and to explore crypto payments for Japanese travelers.
his Japan Korea Stablecoin story has several moving parts, so each is explained below in plain words, along with a related test that the Japanese group announced earlier in October.
The agreement has four signers: KB Kookmin Card, SBI Holdings, the Korean security firm Everspin, and SBI Everspin, a joint company the two set up for the Japanese market.
In its announcement,reported by The Block, the card company describes a memorandum of understanding, which is an agreement to cooperate and study ideas.
It is not a product launch, and no start date for customers has been given.
An AI agent is a program that books a table or pays a bill on behalf of a person. Before a shop or a bank lets it act, someone must confirm who it is and what it is allowed to do.
The companies plan to test a platform called KYA, short for “Know Your Agent”, which the joint company planned and is building together with Everspin.
It checks that the agent is real and that it stays inside the limits the user has approved.
The work will go step by step:
First, confirm the identity of Japanese AI agents when they reach Korean services
Next, manage which services each agent may use
Then, study links with KB Pay, the card company’s payment app
The second goal is the one that matters for this Japan Korea stablecoin story. After the identity tests, the partners will study how Japanese visitors could use digital assets, including stablecoins, which are digital coins designed to hold a steady value, at shops in Korea.
They plan to check payment, settlement, cancellations, refunds, and fraud handling and to weigh the legal setting before judging whether a real service is possible. No coin is named.
Rules in Korea for such coins are still being built, as aJapanese group’s release itself admits.
For example, a visitor might ask an AI agent to book a Seoul restaurant and pay, and the shop would need proof that the agent truly has that permission.
That release covers a different project. SBI DigiTrust, the group’s blockchain arm, signed a basic agreement with Korea’s NICE Information & Telecommunication and the Korean blockchain firm DSRV.
They are testing a Japan Korea Stablecoin payment in which a Japanese traveler scans a QR code, the square barcode read by a phone, at a NICE shop in Korea.
The test is due to finish around the end of December 2026.
Company
Role in the test
SBI DigiTrust
Designs the payment plan using Japanese rules and finance know-how
NICE
Brings Korean payment operations and shop network
DSRV
Studies the technical needs and system links
The release describes NICE as Korea’s largest payment company, supporting about 1.2 million shops nationwide.
The release says the test follows real in-store use and studies how money moves from a Japanese user to a Korean shop, what instructions trigger it and how each system connects. It does not say which coin will be used or how many shops will take part.
Both projects are experiments, and the release says results will only inform a later decision on commercial use.
Costs and expected transaction sizes are part of that review. Several questions remain open:
Which coin will be used has not been stated
Korean rules are still under discussion
No launch date has been promised to travelers
The two projects are separate announcements, and no joint service is described
The Japan Korea stablecoin plans show how banks, card firms, and blockchain companies are testing a simple idea: a traveler pays in a shop using digital money, safely and legally.
For now, it is early work built on agreements and trials. Both projects aim at the same goal from different directions: one starts with trust in AI agents, the other with payment at the till.
Watch for results around the end of December, and treat every plan as a plan.
