# TWINT > Source: https://docs.barcoder.ai/docs/standards/twint > research date 2026-05-29 · extracted at 2026-10-06 > Publisher: Barcoder — encyclopedia of QR, barcode and payment-code standards Specifications: - [TWINT — official](https://www.twint.ch/en/) - [TWINT — Wikipedia](https://en.wikipedia.org/wiki/TWINT) ## Overview **TWINT** is Switzerland's dominant mobile payment system, born from the **2016 merger of two competing Swiss mobile payment apps** (PostFinance's Twint and SIX/UBS/Zurich-Cantonal-Bank's Paymit) [1][1], [2][2]. As of 2024 it has **~6 million users** (≈ 65 % of Switzerland's adult population) [3][3] and is unusual among national mobile payment systems for **shipping as ~60 different bank-branded versions** of the same underlying TWINT platform (UBS TWINT, ZKB TWINT, Raiffeisen TWINT, PostFinance TWINT, etc.) [Switzerland report](https://docs.barcoder.ai/docs/payments/CH). TWINT is QR-based: in-store payments by scanning a merchant QR (printed or on a terminal screen), P2P transfers by phone-number lookup, parking/vending via in-app QR flows. TWINT shareholders today: **Banque Cantonale Vaudoise, PostFinance, Raiffeisen, UBS, Zürcher Kantonalbank, SIX Group, Worldline** [1][1] — making it owned by essentially every major Swiss banking-system stakeholder. ## History **Pre-history (2014–2015) — two competing Swiss mobile payment apps emerged**: - **Twint** was created by **Monexio AG**, a company founded **July 2014** as a wholly-owned subsidiary of **PostFinance** (Switzerland's state-owned bank) [1][1]. PostFinance Executive Board member **Thierry Kneissler** became CEO; PostFinance CEO **Hansruedi Köng** became Chairman. - **Paymit** was launched in parallel by **Zürcher Kantonalbank (ZKB) and SIX Group**, with UBS subsequently joining [2][2], [4][4]. **Twint pre-launch and national rollout** [1][1], [4][4]: - **6 August 2015** — Twint pre-launch in Bern and Zurich. - **3 November 2015** — National rollout. - Initial cooperating banks: Berner Kantonalbank, Valiant Bank (2015); joined by Basler Kantonalbank, Bank Cler (2016). **May–September 2016 — Twint + Paymit merger** [1][1], [2][2]: - May 2016: Twint and Paymit announce fusion. - September 2016: Switzerland's Competition Commission (WEKO) approves the merger. - A new entity, **Twint AG**, was founded in September 2016, owned by Banque Cantonale Vaudoise, PostFinance, Raiffeisen, UBS, Zürcher Kantonalbank, SIX, and Worldline [1][1]. The merger was strategically necessary: Switzerland's small market couldn't sustain two competing bank-consortium mobile payment systems. The combined entity took the **Twint** brand and the **Paymit** technical foundation in several areas. **Subsequent growth** [1][1], [3][3], [Switzerland report](https://docs.barcoder.ai/docs/payments/CH): - 2016–2020 — Steady bank adoption; eventually ~40+ banks participating, each shipping their own bank-branded TWINT app version. - 2020 — TWINT crosses several adoption thresholds during COVID-19 (contactless payment preference). - 2023 — ~5 million users [1][1]. - 2024 — ~6 million users [3][3] (~65 % of Switzerland's ~9M population). **2024 context — Credit Suisse merger** [Switzerland report](https://docs.barcoder.ai/docs/payments/CH): - June 2024: Credit Suisse Schweiz merged into UBS Switzerland. - The TWINT shareholder structure consolidated; Credit Suisse TWINT customers transitioned to UBS TWINT. ## Technical specification TWINT is **bank-side proprietary** — the protocol between the TWINT app and TWINT AG's backend is not openly published, and there is no significant open-source TWINT library ecosystem [Switzerland report](https://docs.barcoder.ai/docs/payments/CH). What is publicly documented is the consumer-facing interaction model and the QR code's structural role. **Interaction modes** [1][1], [Switzerland report](https://docs.barcoder.ai/docs/payments/CH): | Mode | Description | |---|---| | **QR scan at POS terminal** | Customer opens TWINT app, scans the dynamic QR shown by the payment terminal, confirms payment in-app | | **QR scan at printed merchant QR** | For small merchants (market stalls, mountain huts, sports-club restaurants); static QR per merchant, customer enters amount | | **Phone number P2P** | Send money to recipient by their Swiss phone number; recipient sees credit in their TWINT app | | **Vending machine QR** | QR on the machine; scan to pay for the product | | **Parking** | QR at parking meter; scan to start parking, app charges per minute, scan/tap to end | | **Online checkout** | Web shops display TWINT as a checkout option; redirect or QR scan flow | **QR code structure**: TWINT QRs use standard [QR Code](https://docs.barcoder.ai/docs/standards/qr-code) symbology (ISO/IEC 18004). The payload encoding is TWINT-proprietary (a specific URL or token format consumed by the TWINT app on the customer's device) — TWINT AG does not publicly document the payload format. **Bank-app architecture** [Switzerland report](https://docs.barcoder.ai/docs/payments/CH): TWINT ships as ~60 separate apps in the Swiss App Stores, each branded for its issuing bank but sharing a common TWINT backend: - **UBS TWINT** — #1 in Switzerland, ≥ 1M users - **ZKB TWINT** — Zürcher Kantonalbank-branded - **Raiffeisen TWINT** — Cooperative banks - **PostFinance TWINT** — State-owned bank (the original Twint legacy) - **+55 more cantonal/regional bank-branded versions** The bank-version proliferation reflects Switzerland's banking landscape — each cantonal bank wants its own branded app for customer identity. The user picks the TWINT version matching their bank when first installing. **Funding sources**: TWINT can be funded by Swiss bank account (most common) or by linking a Swiss credit/prepaid card (UBS TWINT specifically) [Switzerland report](https://docs.barcoder.ai/docs/payments/CH). **Settlement**: For inter-bank TWINT transactions, settlement uses Swiss Interbank Clearing (SIC); since August 2024, **SIC IP (Swiss Instant Payments)** enables sub-10-second settlement [Switzerland report](https://docs.barcoder.ai/docs/payments/CH). ## Use cases TWINT is broadly used across Swiss payment contexts, and notable for reaching into **informal and low-volume merchant categories** that card networks struggle with [Switzerland report](https://docs.barcoder.ai/docs/payments/CH), [1][1]: - **In-store POS at small merchants** — cafés, bakeries, small shops display TWINT QR alongside card acceptance. ~5+ million Swiss users actively use TWINT here. - **Hawker-equivalent informal vendors** — **1,900+ Swiss farm stands (Hofläden)** accept TWINT for honesty-box-style transactions [Switzerland report](https://docs.barcoder.ai/docs/payments/CH). This is structurally where TWINT outpaces card networks: a farm stand can't justify a card terminal but can print a TWINT QR sticker. - **Mountain huts and ski-resort cafés** — TWINT is ubiquitous in Swiss mountain hospitality (no card terminals at altitude, but mobile data + TWINT works) [1][1]. - **Sports clubs and event catering** — *Klub-Restaurants*, festival booths, neighbourhood markets [1][1]. - **Vending machines** — Selecta and other Swiss vending operators have TWINT-compatible QR-pay capability. - **Parking meters and parking apps** — major Swiss cities accept TWINT for street parking and garage parking. - **P2P transfers** — phone-number-keyed; quintessential "I owe you 20 francs for dinner" use case. - **Online commerce checkout** — Swiss e-commerce sites offer TWINT as a payment option alongside credit cards. **Adoption metrics** [1][1], [3][3], [Switzerland report](https://docs.barcoder.ai/docs/payments/CH): - ~6 million users (2024) - ~65 % of Swiss adult population - **Retailer transaction fee**: ~**1.3 %** — has drawn complaints from the Swiss Retail Federation about TWINT's dominant market position [1][1]. ## Implementations TWINT has **no open-source library ecosystem** of consequence [Switzerland report](https://docs.barcoder.ai/docs/payments/CH) — the protocol is gated by TWINT AG, integration is via the TWINT acquirer SDK for merchants, and the consumer-side is bank-app-only. **Production app versions** (canonical implementations) [Switzerland report](https://docs.barcoder.ai/docs/payments/CH): - **UBS TWINT, ZKB TWINT, Raiffeisen TWINT, PostFinance TWINT** — the major bank-branded apps. - **Cantonal bank versions** — ~30+ regional Swiss cantonal banks each ship their own TWINT app. - **Bank Cler TWINT, Migros Bank TWINT**, etc. — non-cantonal alternatives. **Merchant integration**: - TWINT AG provides a **TWINT for Business** acquirer offering, with REST APIs and SDKs for POS terminal integration. - **Worldline** (a TWINT shareholder) is a major Swiss payment processor and acts as TWINT acquirer for many merchants. - **SumUp, Stripe, Adyen** and other international PSPs integrate TWINT as a Swiss-market payment method. **For developers**: TWINT publishes a [developer portal] for partners onboarded via TWINT AG; community-developed open-source libraries are essentially absent, reflecting the gated integration model. ## Comparison **vs. [BLIK](https://docs.barcoder.ai/docs/standards/blik) (Poland)** — Closest peer in design philosophy. Both founded by a consortium of major national banks (TWINT: PostFinance + later all big Swiss banks; BLIK: 6 founding Polish banks), both achieved national dominance, both QR-supported, both non-Eurozone. Differences: BLIK's primary interaction is a 6-digit code (with QR secondary); TWINT is QR-first (with phone-number-P2P secondary). Both demonstrate the bank-consortium-collaboration-required pattern for national mobile payment systems [Poland report](https://docs.barcoder.ai/docs/payments/PL), [Switzerland report](https://docs.barcoder.ai/docs/payments/CH). **vs. [Swish QR](https://docs.barcoder.ai/docs/standards/swish-qr) (Sweden)** — Another bank-consortium national mobile payment system: Swish (2012) is older than TWINT (2015/2016 merger), both Nordic-European, both achieved ~80 % adult-population adoption in their home market. Swish settled on phone-number-as-identifier + QR; TWINT settled on QR + phone-number P2P. Both achieved dominance against card-network and Apple/Google Pay alternatives [Sweden report](https://docs.barcoder.ai/docs/payments/SE), [Switzerland report](https://docs.barcoder.ai/docs/payments/CH). **vs. Apple Pay / Google Pay** — TWINT competes directly with NFC mobile wallets for in-store payment. NFC requires NFC-capable POS terminals; TWINT QR works on any printed sticker, broader merchant base. TWINT's dominant share in Switzerland vs. Apple/Google Pay reflects this merchant-acceptance asymmetry [Switzerland report](https://docs.barcoder.ai/docs/payments/CH), [1][1]. **vs. [Swiss QR-bill](https://docs.barcoder.ai/docs/standards/swiss-qr-bill)** — Complementary, not competing. Swiss QR-bill is for printed-invoice asynchronous payment; TWINT is for in-person / online mobile payment. Both are operated by SIX-adjacent entities (SIX is a TWINT shareholder); both are universal in Switzerland in their respective contexts [Switzerland report](https://docs.barcoder.ai/docs/payments/CH). A Swiss consumer typically uses TWINT for café/parking/P2P and Swiss QR-bill for the monthly utility invoice. ## Fun facts TWINT's "**~60 bank-branded app versions**" is unique among national mobile payment systems [Switzerland report](https://docs.barcoder.ai/docs/payments/CH) — most peer systems (Pix, UPI, BLIK, Swish) have one or a handful of authorised apps. The proliferation reflects Switzerland's bank concentration around **cantonal banks** (one per canton, each fiercely preserving its identity). When TWINT consolidated, each cantonal bank wanted its own branded app rather than directing customers to a single "TWINT app." The shared TWINT backend makes this work — same protocol, different brand identity. TWINT was the result of **two competing Swiss mobile payment apps merging because the country was too small to support two** [1][1], [2][2]. PostFinance built Twint; SIX + ZKB + UBS built Paymit. Both launched 2015 and competed for ~18 months until the May 2016 merger announcement. The combined entity (Twint AG, September 2016) brought every major Swiss banking-system stakeholder into one shareholder structure — arguably more important than the technical merger itself. **1,900+ Swiss farm stands (Hofläden) accept TWINT** [Switzerland report](https://docs.barcoder.ai/docs/payments/CH) — a use case where the printable-QR-sticker advantage over card-terminal infrastructure is most visible. The Swiss tradition of unattended honesty-box-style farm stands selling apples, eggs, and cheese converts naturally to "scan the QR, pay the price on the sign, take the produce." This is a structural reason why TWINT became a *cultural* feature in rural Switzerland, not just an urban one. TWINT's **~1.3 % retailer fee** has drawn formal complaints to the Swiss Competition Commission from the Swiss Retail Federation about market dominance [1][1]. This is a recurring tension for national mobile payment systems that grow into critical-infrastructure status: the network-effect lock-in that drove adoption also creates merchant-side pricing power that attracts regulatory scrutiny. ## Status **Active and dominant in Switzerland.** Most recent figures [1][1], [3][3], [Switzerland report](https://docs.barcoder.ai/docs/payments/CH): - **~6 million users (2024)** — approximately 65 % of Switzerland's adult population - **Universal Swiss banking-system participation** via ~60 bank-branded app versions - **Settlement via SIC and SIC IP** (Swiss Instant Payments, live August 2024) — sub-10-second settlement - **Merchant acceptance** across retail, hospitality, farm stands, vending, parking, e-commerce **Strategic context** [Switzerland report](https://docs.barcoder.ai/docs/payments/CH): - Credit Suisse Schweiz merged into UBS Switzerland in June 2024 — TWINT customers consolidated under UBS TWINT. - Switzerland exploring **ECB TIPS link** for EUR-denominated SEPA-area instant payments — would extend TWINT's potential cross-border reach into the eurozone, though no concrete TWINT cross-border feature has been announced. - No deprecation planned; TWINT is positioned as durable Swiss national mobile payment infrastructure. The retailer-fee criticism remains an active regulatory question, but Swiss antitrust review (WEKO) has not (as of mid-2025) found grounds for intervention beyond ongoing oversight [1][1]. ## Sources [1]: https://en.wikipedia.org/wiki/TWINT [2]: https://www.finews.com/news/english-news/23069-swiss-mobile-payment-solution-twint-paymit [3]: https://www.swissinfo.ch/eng/various/twint-has-more-than-six-million-users-by-the-middle-of-the-year/89856828 [4]: https://www.twint.ch/en/press/twint-become-switzerlands-digital-wallet/ [5]: https://www.twint.ch/en/press/even-banks-counting-twint/ [6]: https://neobanque.ch/blog/twint-swiss-mobile-payment-revolution/ [7]: https://www.twint.ch/en/ [8]: https://one.oecd.org/document/DAF/COMP/WD(2025)41/en/pdf [9]: https://www.bluewin.ch/en/news/twint-has-more-than-six-million-users-at-mid-year-2832312.html [ch-cro]: https://docs.barcoder.ai/docs/payments/CH [pl-cro]: https://docs.barcoder.ai/docs/payments/PL [se-cro]: https://docs.barcoder.ai/docs/payments/SE 1.
