SGQR

Overview

SGQR is Singapore's national unified payment QR code — the world's first to combine multiple e-payment schemes into a single QR label ^{1, 2}. A merchant displays one SGQR sticker; the customer's app — whatever scheme it supports — finds its own routing information inside the same QR and processes the payment. The taskforce was formed in August 2017 by the Payments Council, co-led by the Monetary Authority of Singapore (MAS) and the Infocomm Media Development Authority (IMDA), and SGQR launched in September 2018 ^{1, 3}. The technical foundation is the EMVCo "QR Code Specification for Payment System — Merchant-Presented Mode" issued by EMVCo in July 2017, with Singapore-specific extensions ¹.

In November 2024 an enhanced SGQR+ variant launched, expanding to 24+ participating schemes including cross-border ones like DuitNow (Malaysia) and PromptPay (Thailand) ^{Singapore report, 4}.

History

The Singapore Payments Council convened the SGQR taskforce in August 2017, with participation from MAS, IMDA, payment schemes, issuers, acquirers, banks and government agencies ¹. The taskforce was chartered to solve a specific consumer-experience problem: by 2017 Singapore merchants commonly displayed 3–5 separate QR stickers (one per scheme — DBS PayLah!, NETS, GrabPay, Alipay, etc.), creating clutter and forcing consumers to manually check which scheme their app supported ¹.

SGQR launched in September 2018 and rolled out across Singapore over the following six months ¹. The launch was promoted as a world first — no other country had previously deployed a single QR carrying multiple-scheme routing data ².

The system has been extended since:

• 2024 (November): SGQR+ launched, expanding to 35,000+ acceptance points and 24+ schemes, with cross-border QR connectivity to Malaysia, Thailand, Indonesia, China and India ^{Singapore report, 4}.
• Ongoing additions of cross-border partners (PayNow↔UPI link with India was operational at launch of SGQR+) ^{Singapore report}.

Technical specification

SGQR adopts EMVCo "QR Code Specification for Payment System — Merchant-Presented Mode" (July 2017) with Singapore-specific customisations ^{1, 5}.

EMVCo MPM foundation ⁵:

• Payload format: TLV (Tag-Length-Value) plain-text string
• Integrity: CRC-16/CCITT-FALSE appended as final field
• Each "merchant account information" template (tags 02–51) describes one payment scheme's routing data; multiple templates coexist in one QR for SGQR's multi-scheme purpose

Singapore-specific customisations documented in the MAS/IMDA fact sheet ¹:

• Default positions for Singapore-relevant fields within the EMVCo TLV layout
• Guidance on EMV-specific fields beyond what the global spec requires
• Ordering of merchant-account-information templates for code efficiency — the most common Singapore schemes appear earliest
• A standardised SGQR label design with the schemes' icons surrounding the central QR, so a consumer sees at a glance which apps will work

Currency / country: SGD (702) and SG are the default values ⁵.

Use cases

SGQR is the point-of-sale QR standard for Singapore. Essentially every merchant accepting QR payments uses it:

• Retail point of sale — small merchants (hawker centres, market stalls, taxis, neighbourhood shops) display a printed SGQR label and accept any of the participating schemes ^{Singapore report}.
• F&B and hawker centres — government promoted SGQR aggressively in hawker centres as part of the cashless-society push; a 0.5 % transaction-fee subsidy ran through December 2024 to drive merchant adoption ^{Singapore report}.
• E-commerce — dynamic SGQR generated server-side per cart, displayed on the checkout page.
• Bill payments — utilities, government fees, school fees.
• Cross-border tourism — via SGQR+, inbound tourists from Malaysia, Thailand, Indonesia, China, India can scan SGQR with their home banking apps and pay seamlessly ^{Singapore report}.
• PayNow QR overlay — every SGQR also carries a PayNow merchant identifier where applicable, so a customer with a Singapore bank account can pay via instant interbank transfer ^{Singapore report}.

Implementations

The SGQR scheme is operationally closed — merchants get SGQR labels through their acquirers (NETS, banks) rather than self-generating — so the open-source library ecosystem is thinner than for, say, Pix or EPC QR.

Encoder / decoder:

• Java — hisenyuan/EMVCo-SGQR-encode-decode-crc — 17★, last commit 2024. Encodes and decodes SGQR / EMVCo MPM payloads, including the CRC calculation. Supports parsing Singapore merchant-account-information templates for Alipay, WeChat Pay, UnionPay ⁶. The repository ships actual sample SGQR data extracted from production Singapore merchants for testing.

General EMVCo MPM libraries that can read SGQR (since SGQR is EMVCo MPM with Singapore-specific tag values, any compliant decoder works):

• Most national QR library implementations (e.g. thalesog/pix-utils, dtinth/promptpay-qr) can be adapted with minor tag-handling changes [pix-utils].

Bank apps — the dominant production "implementation" is via Singapore bank apps: DBS PayLah!, OCBC Digital, UOB TMRW, NETS app, GrabPay. These scan SGQR natively and route through the appropriate scheme based on the user's selection ^{Singapore report}.

Hosted services: NETS issues SGQR labels via its merchant-onboarding workflow ^{Singapore report}.

Comparison

vs. DuitNow QR (Malaysia) and PromptPay QR (Thailand) — All three share the same EMVCo MPM technical foundation (the spec EMVCo issued in July 2017), launched within a 12–18 month window, and are operated by their respective central-bank-affiliated payment infrastructure. The differences are in which schemes share the QR: SGQR is unusually broad with 24+ schemes including international card networks; DuitNow is mostly Malaysian banks + e-wallets; PromptPay is bank-only ^{Singapore report, Malaysia report, Thailand report}. Cross-border interoperability between them was achieved via direct bilateral integrations announced in 2023–2024 ^{Singapore report}.

vs. Bharat QR (India) — Bharat QR also uses EMVCo, but India runs a separate dominant UPI QR rail (a upi://pay?... deep link, not EMVCo). SGQR has no equivalent fragmentation: every SG payment QR is SGQR-compliant by mandate ^{Singapore report}.

vs. earlier per-scheme QRs (e.g. NETS QR, separate Alipay QR, separate WeChat QR) — Pre-2018 a Singapore merchant had to display one sticker per scheme they wanted to accept (often 3–6 stickers). SGQR collapses these into one. This is the actual product-market problem SGQR was built to solve ¹.

Fun facts

SGQR was the world's first unified multi-scheme payment QR code ². The taskforce explicitly studied earlier national QR rollouts — Thailand's PromptPay (launched 2016, single-scheme) and India's Bharat QR (launched September 2016, multi-card-network but not e-wallets) — and concluded none had solved the merchant-clutter problem the way Singapore wanted to ¹.

The SGQR design was so successful that EMVCo cited it as a reference implementation when promoting its MPM specification for adoption by other national rollouts that followed (DuitNow 2019, QRIS 2019, ASEAN cross-border 2022) ². The Bank for International Settlements' Project Nexus initiative for multilateral cross-border QR connectivity counts SGQR's bilateral-link approach as part of its foundational design ^{Malaysia report}.

By 2024 only 13 % of point-of-sale transactions in Singapore involved cash, with projections of 8 % by 2030 ^{Singapore report} — a transition that SGQR's universal acceptance directly enabled.

Status

Active and expanding. SGQR remains the canonical merchant QR standard in Singapore. The November 2024 SGQR+ expansion added 24+ schemes and 35,000+ enhanced acceptance points, signalling ongoing investment rather than maintenance mode ^{Singapore report, 4}. Sectoral expansion in May 2025: SGQR reached 27 public hospitals and polyclinics, extending beyond hawker centres and retail into the healthcare-payment surface ^{Singapore report}. Broader NETS SGQR acceptance has reached ~40,000 outlets as the overlap between base SGQR and SGQR+ continues to grow. Cross-border QR connectivity now spans Malaysia (DuitNow), Thailand (PromptPay), Indonesia (QRIS), China (Alipay, WeChat), and India (via the PayNow↔UPI link) ^{Singapore report}.

The 2018-era specification (v1.x) remains the technical baseline; the SGQR+ rollout extends scheme participation rather than changing the underlying TLV format. No deprecation planned; Singapore's MAS continues to position SGQR as a model for other countries' unified-QR efforts ².
