Overview

KHQR (Khmer QR) is Cambodia's national EMV QR payment standard, operated by the National Bank of Cambodia (NBC) and built on the Bakong blockchain-based central-bank-controlled payment infrastructure [1, 2, kh-cro]. Bakong launched in October 2020 as the world's first central-bank-controlled DLT-based ("CBDC-like") retail payment system, built jointly by NBC and the Japanese blockchain company Soramitsu on the Hyperledger Iroha framework [3, 4]. KHQR followed in July 2022 as the EMV-compliant QR overlay on top of Bakong, providing unified merchant-side QR acceptance across all participating institutions [3, kh-cro].

By 2024 the Bakong+KHQR ecosystem had 30 million wallets, 4.5 million accepting merchants, and processed $104.81 billion in 608 million transactions — an extraordinary 330 % of Cambodia's GDP in transaction value KH. Cross-border KHQR connectivity is the most extensive of any small-country payment system: live or active with Thailand, Malaysia, Vietnam, Laos, Singapore, South Korea, China (Alipay+) and with India UPI link planned for H2 2026 KH.

History

2016 — NBC begins CBDC work [3]: The National Bank of Cambodia inaugurates Project Bakong — its central-bank-digital-currency-like initiative. Cambodia's payment landscape at that time was challenging: dual-currency (KHR + USD widely circulating), low banking penetration, mobile money fragmented across multiple operators, and ongoing dollarization concerns from the central bank.

2017 — NBC selects Hyperledger Iroha [3]: After evaluating distributed-ledger options, NBC chose Hyperledger Iroha (a blockchain platform written in C++ by Soramitsu) as the ideal DLT for retail CBDC use. The collaboration with Soramitsu (Japanese fintech, also LFDecentralizedTrust contributor) ran from 2017 onwards.

July 2019 — Bakong pilot [3]: Pilot project launched with 10,000+ users, running successfully through 2019–2020.

October 2020 — Bakong public launch [3, 4]: Bakong officially launched to the public. The system supports both KHR and USD, P2P/P2B/B2B transfers, and cross-border connectivity. Designed explicitly to support de-dollarization — by making KHR digital payments easier than USD cash, NBC nudges consumer / merchant preference toward KHR.

July 2022 — KHQR launches as Bakong's QR overlay [3]: NBC introduces KHQR as the EMV-compliant unified QR layer on top of Bakong. Single QR accepts payments from all 57 participating financial institutions and mobile money operators.

Subsequent milestones [kh-cro, 5]:

2023 — Cross-border KHQR with Thailand (PromptPay), Vietnam (VietQR), Laos (LaoQR) active.
2024 — Cross-border with Malaysia (DuitNow) live; South Korea (Kakao Pay) live August 2024.
August 19, 2024 — Bakong Tourists App launched in Siem Reap, enabling foreign visitors to make payments via Bakong's network using their home banking credentials.
November 2024 — Mastercard integration with Bakong Tourists App.
January 22, 2025 — Visa integration with Bakong Tourists App.
March 2025 — Japan JPQR Global MoU signed for cross-border QR.
2025 — Cambodia-Singapore (RoamQR) Phase 1 launched.
H2 2026 planned — India UPI cross-border link.
2024 KHR transactions grew 334 % KH — direct evidence Bakong's de-dollarization push is succeeding; 49 % of transactions are now in KHR.

Technical specification

KHQR is an EMVCo Merchant-Presented Mode (MPM) compliant QR overlay on top of the Bakong blockchain-based payment rail [3, kh-cro]:

Layer	Description
Underlying rail	Bakong — distributed-ledger-technology payment system on Hyperledger Iroha
DLT framework	Hyperledger Iroha (C++) by Soramitsu (Japan)
Settlement	Real-time via Bakong; 24/7/365
Currency support	KHR and USD (dual-currency native)
QR format	EMVCo MPM TLV
Underlying symbology	qr-code (ISO/IEC 18004)
Currency codes	116 (KHR), 840 (USD)

EMVCo MPM foundation [5]:

Payload format: TLV (Tag-Length-Value) plain-text string
Integrity: CRC-16/CCITT-FALSE appended as field 63
Static and dynamic QR variants supported

Modes [kh-cro, 3]:

Merchant-presented QR (static) — printed sticker per merchant; customer enters amount.
Merchant-presented QR (dynamic) — POS-generated per transaction with amount embedded.
Consumer-presented QR — customer's app displays QR for merchant POS to scan.
Cross-border — KHQR-Global variant for inbound foreign tourist payments via bilateral integrations.

Bakong's distinguishing technical features [3, 4]:

Hyperledger Iroha blockchain — distributed ledger for transaction recording; not a public chain but a permissioned-DLT operated by NBC.
Dual-currency native — every Bakong account holds separate KHR and USD balances; user can pay in either currency seamlessly.
No transaction fees for P2P transfers (NBC subsidises the rail).
57 participating financial institutions as of 2024 — all major Cambodian banks + mobile money + microfinance institutions.

Use cases

KHQR's deployment spans the entire spectrum of Cambodian commerce, with notable strength in tourism payments [kh-cro, 3]:

Retail point of sale — every kind of merchant from market vendors to chain supermarkets. 4.5 million accepting merchants in a country of ~17 million population — extraordinarily high merchant-per-capita density.
Tuk-tuk and motodop (motorcycle taxi) payments — QR sticker on the driver's phone or vehicle accepts fare via KHQR scan.
Street food and informal commerce — printable-QR-sticker advantage works at otherwise-untrackable transaction points.
Bill payments — utilities, telecom, government fees.
Tourism payments — Bakong Tourists App (launched August 2024) enables foreign visitors to pay at KHQR merchants using their home bank credentials via the Mastercard / Visa integration. Particularly important for the Siem Reap (Angkor Wat) tourist economy.
Cross-border — Cambodian Bakong users paying foreign merchants via the bilateral cross-border QR network (Thailand, Vietnam, Laos, Malaysia, Korea, China-via-Alipay+).
Government disbursement — social benefit payments increasingly routed through Bakong wallets.
De-dollarization — every KHQR transaction in KHR rather than USD reinforces the riel's domestic currency role.

Scale (2024) KH:

30 million Bakong wallets
4.5 million accepting merchants
608 million transactions in 2024
$104.81 billion value — 330 % of Cambodia's GDP
+95 % growth from 2023
KHR transactions grew 334 % in 2024 (de-dollarization signal)
49 % of transactions now in KHR (vs USD)

Implementations

KHQR's open-source library ecosystem is thin; production integration goes through NBC + Soramitsu + bank-acquirer channels [kh-cro, 3].

Production apps consuming KHQR KH:

App	Provider	Notes
Bakong	NBC	Official central-bank wallet
ACLEDA Mobile	ACLEDA Bank (largest Cambodian bank)	KHQR-enabled
ABA Mobile	ABA Bank	Digital banking leader
Wing	Wing	Mobile money pioneer
TrueMoney	TrueMoney	Cross-border-capable wallet
Bakong Tourists App	NBC (foreign visitors)	Mastercard + Visa integration

General EMVCo MPM libraries can read KHQR payloads (since KHQR is EMVCo MPM with Cambodian merchant-account-information templates) — same compatibility pattern as sgqr, promptpay-qr, qris, duitnow-qr, vietqr.

Soramitsu [3, 4] — the Japanese fintech that built Bakong's Hyperledger Iroha foundation continues to provide technical support; the Soramitsu case study with Hyperledger is the canonical technical reference for Bakong's architecture [3].

Acquirer / merchant onboarding:

Each of the 57 Bakong participating institutions handles its own merchant onboarding.
ACLEDA Bank (the largest Cambodian bank) is a particularly important KHQR acquirer.
International PSPs increasingly support KHQR for cross-border merchant integration.

Comparison

vs. ASEAN EMVCo MPM family (sgqr, duitnow-qr, promptpay-qr, qris, vietqr) — Same technical family; same central-bank-affiliated operator pattern; same EMVCo MPM TLV foundation. KHQR's distinctive features:

Built on Hyperledger Iroha blockchain — most peers use traditional payment rails (SCT Inst, RTGS, IPS). Bakong's DLT-based architecture is structurally different.
Dual-currency KHR + USD native — peers handle a single domestic currency.
De-dollarization motivation — peers don't share this strategic context.
Cross-border breadth — KHQR has 9+ active or pending cross-border integrations, possibly the most of any small-country payment system.

vs. pix (Brazil) — Both central-bank-operated national instant payment systems. Pix is much larger (250B+ vs Bakong's 608M annual transactions, but Cambodia's population is ~17M vs Brazil's ~215M), and uses standard SCT-style rails rather than DLT. Pix and Bakong launched within a year of each other (Pix: November 2020; Bakong: October 2020). Different technical architectures, comparable national-scale ambitions [pix-ref].

vs. upi-qr (India) — Both regulator-orchestrated national QR systems; UPI uses a upi://pay?... URI rather than EMVCo TLV. India-Cambodia bilateral UPI ↔ KHQR link planned for H2 2026 [in-cro, kh-cro].

vs. e-CNY (China digital yuan) and other CBDCs — Bakong is often cited as the world's first deployed CBDC-like retail payment system [6, 3], though purists distinguish:

Bakong: NBC controls the system, settles in commercial-bank money (the assets users hold are still bank deposits at participating banks, not direct central-bank claims) → CBDC-like but not strictly a CBDC.
e-CNY (China): users hold direct claims on the People's Bank of China → strict CBDC.

The distinction matters for monetary-economics analysis but operationally Bakong looks and feels like a CBDC to users. NBC and many observers describe Bakong as the world's first deployed central-bank-controlled digital currency at retail scale [6].

vs. m-pesa-ke (Kenya) — Both are dominant African / Asian mobile-money-class systems with large unbanked-population financial-inclusion impact. M-Pesa is older (2007), Bakong is newer (2020), but Bakong's central-bank-controlled DLT architecture is structurally more advanced. Both achieve massive merchant density relative to country population [m-pesa-ref].

Fun facts

Bakong is often cited as the world's first deployed CBDC-like retail payment system [6, 3] — launched October 2020 by NBC + Soramitsu on Hyperledger Iroha. The World Economic Forum and various central-banking publications have profiled Bakong as showing the rest of the world's central banks the path to retail CBDC deployment. Subsequent CBDC pilots and launches (e-CNY in China, Sand Dollar in Bahamas, JAM-DEX in Jamaica, Pakistan's pilot, etc.) all reference Bakong as a structural precedent.

$104.81 billion in 608 million transactions = 330 % of Cambodia's GDP KH — one of the most extreme transaction-value-to-GDP ratios of any national payment system. The high ratio reflects:

High velocity of money flowing through Bakong (the same dollar / riel moves through many transactions).
Cross-border tourism inflows.
Domestic commerce + remittance flows + government disbursements all routing through Bakong.

KHR transactions grew 334 % in 2024; 49 % of Bakong transactions are now in KHR KH — concrete evidence that NBC's de-dollarization-via-Bakong strategy is working. Pre-Bakong (2019), Cambodia's economy was ~80 % USD-denominated for retail transactions; the Bakong push toward KHR-denominated digital payments is slowly reversing dollarisation through user-experience design (KHR Bakong payments are easier than USD cash for everyday commerce).

Soramitsu's name comes from a Japanese pillow-word (枕詞) — an ancient poetic epithet historically used for "Yamato" (Japan) and roughly meaning "filling the sky" / "abundant with sky"; the company invokes this for the metaphor of "building blockchain infrastructure that encompasses the world". The Japan-Cambodia central-bank-and-blockchain-company partnership is structurally unusual; most national payment systems are built by domestic technology companies. Soramitsu's involvement made Bakong an early Asian deployment of Japanese-developed Hyperledger Iroha at scale.

Cambodia is the most cross-border-QR-connected small country in the world KH — 9+ active or pending bilateral / multilateral QR integrations across ASEAN, East Asia (Korea, Japan, China-via-Alipay+), and South Asia (India UPI planned H2 2026). For a country of 17 million, this cross-border breadth is exceptional and structurally important: Cambodia's tourism economy + remittance inflows + cross-border-trade integration all benefit from QR-payment interoperability.

The Bakong Tourists App (launched August 19, 2024 at Siem Reap — the gateway to Angkor Wat) KH is one of the more product-novel offerings in the national-QR-payment space. Foreign tourists who would normally need to exchange cash to KHR / USD before arrival can instead use their home Mastercard or Visa to fund a temporary Bakong wallet, then pay KHQR merchants in Cambodia using the same wallet. This is structurally different from the Alipay+ cross-border model (which routes through partner wallets in the visitor's home country); Bakong Tourists is a temporary in-country wallet provisioned for the visitor.

Status

Active, scaling fast, internationalising aggressively [kh-cro, 3]:

30 million Bakong wallets
4.5 million accepting merchants
608 million transactions (2024) — +95 % YoY
$104.81 billion transaction value (2024) — 330 % of GDP
KHR share growing: 49 % in 2024, +334 % KHR growth
9+ cross-border QR integrations (Thailand, Malaysia, Vietnam, Laos, Singapore, Korea, Japan-via-JPQR-MoU, China-via-Alipay+, India H2 2026 planned)
Bakong Tourists App with Mastercard (Nov 2024) + Visa (Jan 2025) integration

Strategic trajectory KH:

Continued de-dollarization — KHR share continues to grow as Bakong reduces USD-cash dependence.
India UPI link for H2 2026 — extends cross-border footprint into South Asia.
Multilateral Project Nexus (BIS-coordinated) — Cambodia is engaging with the broader ASEAN cross-border payment-coordination initiative.
Continued Hyperledger Iroha evolution — Soramitsu continues to support NBC with technical upgrades to the underlying DLT.

No deprecation planned. KHQR + Bakong is one of the most strategically-distinctive national payment systems globally, demonstrating that a small country can build world-class payment infrastructure with the right combination of central-bank political will, fintech partnership (Soramitsu), and modern DLT architecture.
