ZaloPay QR
ZaloPay QR
Overview
ZaloPay QR — branded "QR đa năng" (multi-function / universal QR) — is the merchant-payment QR format used by ZaloPay, a leading Vietnamese e-wallet operated by VNG Corporation 1, 3. It is an EMVCo Merchant-Presented Mode (MPM) payload: a single printed code that the customer can pay either in the ZaloPay super-app or, because the same code embeds a VietQR-compatible template, in any of 40+ NAPAS-member bank apps 1, 2. ZaloPay launched the format in July 2023 in cooperation with NAPAS, and within six months it was live in over 12,000 store chains, with about 19 % of its transactions coming from bank apps rather than the ZaloPay wallet 3, 5. ZaloPay is Vietnam's second-largest e-wallet (after MoMo), reporting 14 million users in 2024 3.
History
ZaloPay grew out of VNG Corporation (founded 9 September 2004 as VinaGame; Vietnam's first tech unicorn at a US$1 B valuation in 2014) and its Zalo messaging app (released 8 August 2012 for iOS/Android, reaching 10 million users within 18 months) 7. ZaloPay itself was launched by VNG in 2016 as a mobile payment application built on top of the Zalo user base 7, 3. The product is operated by the legal entity ZION Joint Stock Company, VNG's payments subsidiary 8.
Mid-2023 — VietQR disruption. ZaloPay recognised the market shift caused by the rapid growth of VietQR (NAPAS's national interbank QR, which scaled fast through 2023) and responded by building a QR that works on the VietQR rails rather than competing with them 3.
July 2023 — "QR đa năng" launched. ZaloPay was one of the pioneers cooperating with NAPAS to launch a multi-function QR based on the VietQR standard, accepting payments from all banking apps and e-wallets 2, 3.
Within six months (by early 2024). The format reached 12,000+ store chains — including major fast-food and convenience-store networks — and recorded roughly 19 % of transactions through bank apps 3, 5.
2024. ZaloPay reached 14 million users and launched a new brand identity oriented toward sustainable financial products 3.
Mid-2025. ZaloPay reported ~20 million active users through deeper Zalo-chat integrations (bill splitting, gifting), and ~12 million digital red envelopes ("lì xì") were sent through the wallet during Lunar New Year alone 9. ZaloPay sits within a top-five (MoMo, ZaloPay, ViettelPay, ShopeePay, VNPay) holding the bulk of Vietnam's US$40.5 B mobile-payments market 9.
Technical specification
ZaloPay QR follows the EMVCo Merchant-Presented Mode (MPM) TLV (tag–length–value) structure — the same container family used by VietQR and QRIS 1, 4:
- Tag 00 — Payload Format Indicator (
01) 4. - Tag 01 — Point of Initiation Method (
11static,12dynamic) 4. - Tags 26–51 — Merchant Account Information templates. Each begins with sub-tag
00carrying a globally unique identifier (GUID) 4.- ZaloPay's native template is keyed by the ASCII GUID
vn.zalopay1, 4. - A parallel VietQR template carries the GUID
A000000727(NAPAS) with beneficiary identifier9704...routed via partner bank BVBank (Ban Viet Bank) — each ZaloPay merchant is assigned a corresponding BVBank account so bank apps can settle over NAPAS 2, 4.
- ZaloPay's native template is keyed by the ASCII GUID
- Tag 52 — Merchant Category Code.
- Tag 53 — Transaction currency (
704= VND) 4. - Tag 54 — Transaction amount (omitted for static codes) 4.
- Tag 58 — Country code (
VN) 4. - Tags 59 / 60 — Merchant name and city 4.
- Tag 62 — Additional data (reference label, bill number) 4.
- Tag 63 — CRC-16/CCITT-FALSE checksum over the whole payload 4.
An observed ZaloPay payload begins 000201...26520010vn.zalopay...0010A000000727...9704...QRIBFTTA...5802VN...6304 — i.e. one Merchant Account Information template carrying the vn.zalopay GUID alongside the NAPAS A000000727 VietQR routing data, currency 704, country VN, terminated by a tag-63 CRC 4.
The live playground on this page demonstrates the EMVCo MPM container with ZaloPay's tag-26 template (vn.zalopay). Production ZaloPay merchant codes additionally embed a parallel VietQR template (GUID A000000727, via BVBank) so that non-ZaloPay bank apps can scan and pay the same code; the single-encoder demo shows one template at a time.
Static vs dynamic 1:
- Static — a fixed QR placed at the counter; the customer enters the amount. For stores without a POS, ZaloPay supplies a printed QR with no technical integration required 1.
- Dynamic — generated per-transaction (amount embedded) via the Create Order API, displayed on POS/web/app from the response's
qr_codevalue 1.
Use cases
- In-store merchant payments — the printed "QR đa năng" sticker at the counter, scannable by ZaloPay or any bank app 1, 2.
- POS / e-commerce checkout — dynamic, amount-bearing QR generated server-side per order via ZaloPay's Create Order API 1.
- Cash-on-delivery (COD) collection — ZaloPay's multi-function QR has been deployed for COD orders by courier BEST Express 6.
- Cross-wallet / cross-bank acceptance — because of the embedded VietQR template, any of the 40+ NAPAS-member bank apps can pay the same code 1, 2.
- In-chat P2P transfers and gifting ("lì xì" red envelopes) — ZaloPay is invoked directly from a Zalo conversation; ~12 million digital red envelopes flowed through the wallet during Lunar New Year 2025 9.
- Bill splitting inside Zalo group chats — a feature credited with much of the 2024-2025 user-base growth from 14 M to ~20 M 9.
- Cross-border merchant collection via payment gateways — ZaloPay is exposed as a payment method through global PSPs (e.g. Antom, Nuvei) so non-Vietnamese merchants can accept Vietnamese consumers, using the same EMVCo MPM payload at acceptance time 9.
Implementations
ZaloPay QR codes are generated server-side from the merchant integration: the qr_code value returned by ZaloPay's Create Order API is rendered into the displayed QR 1.

Closed-source apps:
- ZaloPay Merchant (iOS
id1444720973, Androidvn.com.vng.zalopay.mep.merchant) by ZION Joint Stock Company — the merchant-facing app that prints/displays "QR đa năng" and reconciles incoming payments; current release v1.5.0 (May 2026) 8. - The consumer ZaloPay wallet is the primary scanner alongside Zalo itself; bank-app scanning (40+ NAPAS members) is supported by the embedded VietQR template 1, 2.
The genuinely ZaloPay-specific integration is at the PSP layer — issuing the vn.zalopay GUID, opening the shadow merchant account on BVBank so NAPAS can route to it, and reconciling the dual-rail settlement.
Comparison
vs VietQR — VietQR is the NAPAS bank-rail national standard (tag 38 / GUID A000000727); ZaloPay QR is wallet-native (vn.zalopay) but embeds a VietQR template for interoperability, so a single sticker serves both networks 1, 2.
vs MoMo's QR Đa năng — MoMo and ZaloPay are Vietnam's two dominant super-app wallets, and both launched near-identical multi-function QR codes settling through BVBank onto the VietQR/NAPAS rails 2, 3.
vs EMVCo MPM — ZaloPay QR is a wallet-specific profile of the EMVCo MPM specification, distinguished by its vn.zalopay GUID 4.
vs QRIS (Indonesia) — QRIS is a mandated, fully interoperable national EMVCo-MPM scheme; ZaloPay QR is a single Vietnamese wallet's merchant code that achieves interoperability by voluntarily co-embedding the VietQR template 1, 2.
vs Alipay QR (China) — Both are super-app-issued merchant QRs (Alipay/Alipay+ for Chinese tourists; ZaloPay for Vietnamese consumers), and ZaloPay QR is one of the in-Vietnam codes Alipay+ can scan as part of cross-border tourist acceptance. The choosing criterion for a Vietnamese merchant: ZaloPay QR plus the embedded VietQR template covers the domestic + bank-app payer base, while Alipay+ acceptance layers on inbound Chinese tourism — distinct payer audiences rather than overlapping rails 3, Viet Nam report.
vs SIB UPI QR (India) / BKM Express QR (Turkey) — single-issuer overlays on a national standard — All three are the same architectural pattern: a single private issuer (ZaloPay/VNG, South Indian Bank, BKM Express) deploys a merchant QR that piggybacks on the national interoperable QR (VietQR / UPI QR / TR Karekod) without inventing a new wire format. The choosing criterion at standard-design time: embed the national template to be scannable by every bank app; add your own GUID template to retain wallet-side routing economics. ZaloPay sits in the same family of design decisions 9, Viet Nam report.
Fun facts
A single ZaloPay "QR đa năng" can be paid by both ZaloPay users (via the vn.zalopay template) and ordinary bank-app users (via the embedded VietQR template), so one printed sticker serves two networks at once 1, 2.
Rather than fight VietQR's 2023 surge, ZaloPay chose to ride it — building its merchant QR on top of the national rail it might have competed with, and within six months was routing ~19 % of "its" QR transactions through rival bank apps 3, 5.
Both MoMo's and ZaloPay's multi-function QR codes settle through the same partner bank, BVBank, which issues each wallet merchant a shadow bank account so NAPAS can route to it 2.
The QR rides a messaging app's user graph. ZaloPay sits inside Vietnam's dominant messenger Zalo (10 M users within 18 months of its 2012 launch, deep penetration since) — and the wallet's 2024-2025 jump from 14 M to ~20 M users was driven primarily by in-chat features like bill splitting and "lì xì" gifting rather than merchant acquisition; ~12 million digital red envelopes were sent through ZaloPay during Lunar New Year 2025 7, 9.
Operated by a gaming-company subsidiary. ZaloPay is run by ZION Joint Stock Company — a subsidiary of VNG, originally founded as VinaGame in 2004 and Vietnam's first tech unicorn. The same legal structure that publishes online games is the regulated payment institution behind the QR 7, 8.
Status
Active and widely deployed across Vietnamese merchants 1, 3. ZaloPay remains Vietnam's second-largest e-wallet (14 million users, 2024) behind MoMo, within a top-five (MoMo, ZaloPay, ViettelPay, ShopeePay, VNPay) that holds the bulk of the market 3. No deprecation is indicated; the multi-function QR is ZaloPay's primary merchant-acceptance surface and is documented as a current product on docs.zalopay.vn 1.
