On October 27, 2026, Shinhan Card began a token payment trial that moves web3 payments out of crypto-native apps and into a real merchant setting. Employees in Seoul are now paying with tokens issued by the card company itself, scanning a QR code from a blockchain wallet without entering an address or initiating a manual transfer. The trial is the first concrete evidence that a national card issuer is testing direct wallet-to-merchant infrastructure on a public blockchain—a card issuer crypto payment experiment that rewrites what founders and finance leads should expect from treasury and vendor payment workflows over the next two years.

What just happened
Oct 27: Shinhan Card starts token payment trial on GIWA Chain
Shinhan Card and digital asset company Dunamu launched a live payment test at a merchant inside Shinhan Card’s headquarters in Jung-gu, Seoul (Shinhan Card to Test Token Payments on Dunamu's GIWA Chain, 아시아경제, October 27, 2026). The test uses Dunamu’s public blockchain, GIWA Chain, and a dedicated wallet app called GIWA Wallet. Shinhan Card issued the tokens directly on Dunamu GIWA Chain and operates them, while Dunamu provides the chain infrastructure and wallet.
QR scan only — no wallet address or transfer step
An employee opens GIWA Wallet, selects the token, and scans a QR code at the store. No wallet address is typed, no separate transfer step is required. The on-chain authentication hides complexity behind the same scan-to-pay expectation people already have with mobile wallets. This design choice targets the friction that has kept blockchain wallet payment experiences locked inside crypto-native circles.
The trial’s realness: employees, a physical store, tokens issued by the card company itself
Real employees receive Shinhan Card tokens and spend them at a physical store. A regulated card issuer is the token issuer—not a crypto exchange, not a merchant coin project—exercising the compliance rails, token lifecycle management, and settlement expectations that would underpin any eventual commercial rollout.
Why it matters for founders and finance leads
Card issuers are the missing middle between crypto apps and merchant POS
Crypto-native QR payments have existed for years—usually inside a single wallet ecosystem. A card issuer sitting between the consumer wallet and the merchant point-of-sale changes the equation. The issuer can handle token issuance, identity checks, and settlement, while the merchant never needs to understand a blockchain. For finance teams, this signals that the infrastructure layer connecting regulated money to on-chain settlement is being built by established institutions, not just crypto startups.
What does a card issuer’s token payment trial mean for real-world merchant acceptance?
Real-world acceptance requires a payment method that fits existing checkout behavior and acquirer networks. Shinhan’s trial demonstrates three ingredients that were missing from earlier efforts: (1) the token is issued and backed by a licensed card company, (2) the payment is completed with a familiar QR scan, and (3) the test runs on a public blockchain with on-chain authentication rather than off-chain ledger reconciliation. If the trial produces acceptable success rates and economics, it opens a path for card-company-issued tokens to plug into standard merchant terminals—no consumer crypto app required. That would turn what was a niche blockchain wallet payment into a mainstream checkout option.
This is not another merchant coin announcement — it is a national card company
Shinhan Card is one of South Korea’s largest credit card issuers with an existing merchant network. The trial moves web3 transactions a step closer to the interchange and settlement systems that already underpin millions of daily payments. When a regulated card issuer tokenizes value on a public chain, it provides a template other financial institutions can adapt for their own tokenized money—including for B2B flows.
What it means for B2B web3 payments, not just retail
While the trial is consumer-facing, the mechanics matter directly for treasury teams. A bank or card company that can issue tokens today for a coffee purchase can issue tokens tomorrow for a vendor payout. The same pattern—tokens settled on-chain, QR-based or address-based payment with minimal friction—maps onto crypto vendor payments and international payroll. As Coinbase’s stablecoin payments push shows, businesses already want to settle invoices in USDC; what’s been missing is regulated-issuer infrastructure that removes the wallet-management burden from both sides.
The background you need to follow this
What are Web3 payments?
Web3 payments are transactions that use blockchain rails, smart contracts, or tokenized assets—typically stablecoins—to transfer value between parties. They can be programmable (escrow, multi-sig), settle peer-to-peer without an intermediary, and tie into decentralized identity (What Are Crypto Payments?, Circle, 2026). This spans both consumer checkout and institutional payout flows.
What is a blockchain payment?
A blockchain payment is any transfer of digital assets recorded on a distributed ledger. While all web3 payments are blockchain payments, not all tap smart contracts or identity layers. The practical difference for a finance lead is that a plain blockchain payment still demands key management and gas monitoring, while web3 payment infrastructure increasingly abstracts those away.
Web3 payment gateways and where Shinhan differs
A web3 payment gateway (like BitPay) lets merchants accept crypto and optionally convert to fiat. Traditional gateways route card-network transactions; a web3 gateway routes blockchain transactions and often adds an off-ramp layer. Shinhan’s trial is different: it embeds a card issuer as the token issuer and authenticator, suggesting a future gateway that doesn’t merely process crypto but originates regulated tokens. This is a significant step beyond the typical card issuer crypto experiment.
Wallet-based QR payments exist but stay crypto-native
QR code wallet payments aren’t new, but they’ve stayed confined to crypto conferences and a few merchants because both parties must hold crypto and the recipient must be ready to accept it. Shinhan’s trial punctures that boundary: the wallet is provided by the issuing institution, the tokens are tethered to a regulated card company, and the payment occurs inside a standard workplace store.
Consumer checkout vs. treasury workflows
Treasury workflows are further along. Consumer crypto checkout is still dominated by trials, while stablecoin vendor payouts and programmatic treasury management are already in production at thousands of businesses (Grow Your Business Globally with Crypto and Stablecoins, Stripe). Shinhan’s consumer test signals the kind of infrastructure that will reach B2B sooner than most assume.
What companies can do today
Split your financial setup into a fiat operating account and a compliant crypto on-ramp off-ramp account. Even if you don’t pay vendors in crypto yet, having that ready removes the delay when a counterparty requests USDC settlement. A real-world workflow: convert fiat to USDC (typical fee 0.15–0.5%), send a small test transaction to the vendor’s wallet, then process the full payment on an L2 network like Polygon (settles in 2–5 minutes, costs a few cents). The bottleneck is onboarding: most contractors lack a self-custodied wallet or clarity on tax rules, so you’ll shoulder KYC and address verification. The Crypto Payroll After the Stripe Bitcoin Fraud Case piece details why address validation and onboarding rigor matter—a mis-routed payment can be unrecoverable.
Fees and speeds already beat traditional rails: USDC on L2 costs under $0.10 and takes minutes, versus SWIFT at $20–50 and 3–5 days. But until issuer-issued tokens with embedded identity become widespread, the verification tax remains the primary brake on web3 payments for startups.
To prepare now: run a small USDC vendor pilot, build a counterparty playbook for address verification and tax withholding, and monitor issuer-token trials like Shinhan’s and recent regulatory moves—October 2026 GENIUS Act updates (U.S. Congress, October 2026) are creating a compliance floor that could accelerate bank-issued tokens (onesafe.io report). Meanwhile, HSBC’s RedCoin launch (HSBC, 2025) already demonstrated that global banks are exploring tokenized settlement for trade finance, a pattern that will migrate to vendor payouts.
What to watch and what’s still unclear
Will Shinhan publish wallet counts, success rates, or merchant economics?
The trial is opaque until we see metrics: employee uptake, transaction success rate, cost per payment, and whether the merchant sees any advantage over existing card acceptance.
Will Shinhan’s tokens be pegged 1:1 to KRW, or will they float?
The source does not specify, but given Shinhan Card’s role as a regulated issuer, a 1:1 peg to KRW is the most logical approach to maintain parity with fiat and avoid introducing volatility.
How does Dunamu’s GIWA Chain handle privacy and compliance?
GIWA Chain is public, so compliance features are likely built into the wallet app and token issuance layer—off-chain identity checks paired with on-chain settlement records—to meet South Korea’s data protection laws without making the ledger itself private.
Can this system plug into existing card terminals?
The QR-based flow does not require new hardware; a software update to existing terminals that support QR scanning could integrate the token payment. Deep integration with legacy card-network rails, however, would need further development.
What is the cost to the merchant relative to card network interchange?
No official numbers yet, but to gain adoption the issuer will need to offer a significant discount over typical card interchange (which runs 1–3% in many markets). The trial will provide the first internal data on these economics.
Will the trial scale beyond Shinhan’s headquarters?
If success metrics are met, expansion to external merchants is the logical next step. Dunamu’s wallet infrastructure and Shinhan’s merchant relationships make a controlled rollout feasible, but no commitment has been made.
Key Takeaways
- Shinhan Card’s token payment trial on Dunamu GIWA Chain is the first live test of a major card issuer issuing blockchain-based tokens for in-person QR code payments.
- The trial signals that regulated web3 payment infrastructure is extending toward tokenized settlement capable of serving treasury and vendor payout flows, not just consumer checkout.
- To prepare, split your treasury into fiat and crypto on/off-ramp accounts, run a USDC vendor payout pilot, and build a counterparty verification playbook now.
- The main barrier remains onboarding and verification costs; until issuer-based identity tokens reduce that tax, businesses must manually manage receipt compliance.
- Bank-issued payroll and payout token pilots, spurred by legal frameworks like the GENIUS Act, will likely be the B2B follow-on that reshapes cross-border vendor settlement far sooner than retail adoption.
