1. CB (Cartes Bancaires): the French national network

If you remember one thing from this guide, remember CB. Cartes Bancaires — officially GIE CB, a Groupement d'Intérêt Économique founded in 1984 by the major French retail banks (BNP Paribas, Société Générale, Crédit Agricole, BPCE, Crédit Mutuel, La Banque Postale, HSBC France) — operates the domestic French card scheme. CB is not a card brand a consumer chooses; it is the underlying interbank network. Roughly 95% of French cards carry the CB logo on the front, almost always next to a Visa or Mastercard logo.

When a French cardholder buys from a French merchant whose acquirer supports CB, the transaction routes over CB rails — lower scheme fees, lower interchange (capped at 0.2% for consumer debit under EU Regulation 2015/751), and the dispute follows the CB code. If the same card is used on a foreign merchant or a French merchant whose PSP does not support CB acquiring, the transaction routes over the cobrand (Visa or Mastercard), with higher scheme fees and international interchange.

Why CB acquiring matters for foreign sellers

A non-French e-commerce seller using a foreign PSP without CB acquiring will silently pay cross-border-style fees on every French transaction, even though the buyer is French and the goods are sold in France. The math: a Stripe Atlas US account selling to a French buyer routes Visa cobranded internationally — interchange jumps from 0.2% to ~1.1–1.5% on a consumer debit card. On a 100,000 EUR monthly French volume that is 900–1,300 EUR of extra cost per month. Every serious French PSP solves this by acquiring through a French entity:

• Stripe France SAS — CB acquirer since 2018, licensed by the ACPR. Stripe routes French cards over CB automatically.
• Adyen France — CB-enabled, full local acquiring with FR IBAN settlement.
• Worldline — historic French PSP (spun out of Atos), one of the largest CB acquirers in Europe.
• Checkout.com — CB-enabled since 2019, popular with marketplaces.
• HiPay and Lemonway — French specialists, strong on marketplaces and Payment Facilitator setups.

The CB scheme in numbers (2026)

2. Visa & Mastercard cobranded with CB

Outside France, Visa and Mastercard are direct competitors of CB. Inside France, they are partners. Almost every French card is cobranded: it has a CB chip and a Visa or Mastercard chip, and the routing decision is made by the acquirer (or by the cardholder in physical PIN scenarios — the "CB" or "Visa/Mastercard" button on the terminal). E-commerce routing is automatic.

Visa in France

Visa Europe — and Visa France as a local entity — partners primarily with BNP Paribas, Société Générale and La Banque Postale on the issuing side. About 40% of French cards are CB+Visa. Visa runs the Visa Token Service (VTS) used by Apple Pay, Google Pay and Samsung Pay tokenisation, and provides Visa Resolve Online (VROL) for non-CB-routed disputes. In 2025 Visa acquired Tink, the largest European Open Banking aggregator — strengthening the A2A and PIS rails covered in section 8.

Mastercard in France

Mastercard's share grew through the Crédit Mutuel and BPCE issuing relationships — roughly 55% of French cobranded cards carry Mastercard. Mastercard Europe is based in Belgium but operates a Paris office and a strong relationship with French marketplaces (Maestro is largely phased out in France in favour of Mastercard Debit). Disputes route through Mastercom; chargeback liability shifts to the issuer on 3DS2-authenticated transactions just like Visa.

What "cobranded" actually changes for the merchant

At checkout, the buyer sees one card number and one CVV. Behind the scenes, the PSP decides whether to send the auth to CB or to Visa/Mastercard. Best practice in 2026 — for any French-issued BIN, route CB first, fall back to the international cobrand only if CB authorisation fails (intelligent routing or "least cost routing"). Stripe, Adyen and Worldline do this by default; smaller PSPs sometimes do not, which is a hidden cost driver.

3. PayPal in France

PayPal France has been a known quantity for fifteen years and remains the #2 method by share in French e-commerce, behind cards. PayPal Europe Sàrl et Cie SCA is licensed in Luxembourg by the CSSF and passports into France under the EU services directive, with full ACPR notification. The PayPal button is essentially mandatory on any French storefront — A/B tests consistently show +8% to +14% conversion uplift on baskets above 50 EUR when PayPal is offered as a checkout option, particularly for first-time buyers who do not want to share their card data.

PayPal "Payer en 4 fois"

PayPal's homegrown BNPL — "Payer en 4 fois" in France, with no interest for the buyer — is offered on baskets between 30 EUR and 2,000 EUR. The merchant receives full payment upfront and PayPal carries the credit risk, charging a small premium (typically 2.5–3.5% MDR vs the standard PayPal MDR of 1.2% + 0.35 EUR for French volume above 2,500 EUR / month). For fashion, beauty and home decor merchants, "Payer en 4 fois" can shift 6–10% of basket volume out of card and into PayPal.

PayPal chargebacks and Seller Protection

PayPal's dispute window is 180 days (vs 120 days for card schemes), and the merchant defends through the PayPal Resolution Center. Seller Protection covers "item not received" and "unauthorised transaction" if the shipping is traceable to the PayPal-confirmed address — a critical detail for marketplace and dropshipping flows. Zunapro automatically attaches tracking numbers, signed delivery proofs and order screenshots to PayPal disputes.

4. Lydia: the French mobile P2P wallet

Lydia launched in 2013 as a French Venmo / Square Cash competitor — split-the-restaurant-bill via SMS or QR. By 2026 Lydia has over 8 million users and has split into two products under the holding company Lydia Solutions: the historic Lydia P2P app (the social wallet) and Sumeria (launched 2024) — a full-stack neobank with IBAN, debit card, savings, lending and trading. Both are regulated electronic money institutions under ACPR supervision.

Lydia for merchants: where it fits

Direct Lydia checkout integration exists (QR codes, "Payer via Lydia" request links and a basic merchant API), but in 2026 Lydia is not yet a mainstream e-commerce checkout button — it dominates peer payments, restaurant tabs, school cantines and small services. Where Lydia matters for e-commerce merchants is indirectly:

• Many French users fund SEPA Instant transfers from their Sumeria IBAN — so when you offer Open Banking PIS at checkout (section 8), a large share will pay from a Sumeria account.
• Lydia issues prepaid Visa cards used heavily by under-25 buyers — these route as Visa cobranded, with normal IFR-capped interchange.
• Lydia's user base is younger and more mobile-first than the bank-issued card population — when planning a French youth campaign, a Lydia QR + Apple Pay combination converts well.

5. HelloBank and digital banks in France

HelloBank, BoursoBank (formerly Boursorama Banque), Fortuneo, ING France (closed retail in 2022 — but the BIN range still circulates), Monabanq, N26 France, Revolut France and Bunq France form the digital-bank layer of the French market. None of them changes the checkout flow in a structural way — all issue Visa or Mastercard debit cobranded with CB — but their cardholder behaviour is distinctive and worth understanding.

What changes at checkout

Digital-bank customers are typically more tolerant of 3DS2 challenge (they live in the app), more likely to use Apple Pay / Google Pay (90%+ tokenisation rate in some BIN ranges), and more likely to pay via SEPA Instant from the same app once you offer Open Banking PIS. Conversion-wise the main thing to test is removing legacy 3DS1 fallback — digital-bank cards almost never have a non-3DS2 path and a bad fallback can fail otherwise good transactions.

6. PSPs: Stripe France, Adyen, Worldline, Checkout, HiPay

You do not pick a "French PSP" the way you pick a French bank — most leading PSPs in 2026 are CB-acquirer-enabled regardless of headquarters. What matters is the fit between your basket profile, your marketplace footprint and the PSP's local feature set. Here is a 2026 comparison grid.

Stripe France — the easy default

Stripe SAS (Paris) is the easiest PSP to integrate for an English-speaking founder selling to France. CB acquiring is default, payouts hit a FR IBAN in T+2, Radar covers fraud, Connect handles marketplace split payouts, and 3DS2 is automated. Typical pricing: 1.4% + 0.25€ for European cards. Drawbacks: limited true negotiation on rates below ~5M EUR / year, and Stripe does not offer terminal-acquiring for physical retail in France (Worldline / Verifone still own that turf).

Adyen — best for unified commerce

Adyen is the choice when you have a physical-retail leg + e-commerce + marketplace. MarketPay (Adyen for Platforms) handles split payments cleanly under PSD2's payment-facilitator regime. Pricing is negotiated, typically ~1.2% + 0.11€ at scale, with strong Apple Pay / Google Pay tokenisation.

Worldline — the French incumbent

Worldline emerged from Atos, absorbed Ingenico in 2020 and is the dominant retail-terminal acquirer in France. For online-only sellers Worldline is less common, but if you have any physical-store footprint you will end up working with Worldline at some level — and they do support CB acquiring at the most competitive rates for sub-1% blended MDR at high volume.

HiPay and Lemonway — marketplace specialists

HiPay (Paris) and Lemonway (Paris) are French specialists in marketplace and payment-facilitator scenarios. If you are running a multi-vendor marketplace under PSD2 (you receive on behalf of vendors and split payouts), Lemonway is the most common pick — they handle KYC, AML monitoring, escrow and split-settlement under their own ACPR licence. HiPay is comparable and stronger on fraud orchestration.

7. 3DS2, PSD2 SCA — mandatory strong customer authentication

Since 15 May 2021, every remote card payment in the EEA must comply with the Strong Customer Authentication (SCA) requirement under PSD2 RTS (Regulatory Technical Standards). In France this is enforced by the Banque de France and ACPR, with public dashboards on fraud rates published quarterly by the Observatoire de la Sécurité des Moyens de Paiement. In 2026 the SCA regime in France is mature: ~75% of card transactions clear via 3DS2 frictionless (no challenge — risk analysis only), the remaining ~25% go to challenge (app biometric, OTP fallback).

3DS2 in plain language

3D Secure 2 is a protocol — the PSP collects ~150 device, behavioural and transaction signals from the browser, sends them to the issuer's Access Control Server (ACS) over the EMVCo 3DS2 messaging, and the issuer decides "frictionless" or "challenge". A frictionless transaction is invisible to the buyer — no redirect, no OTP, no extra step. A challenge transaction pops the bank's app for biometric (Face ID or fingerprint) or, as fallback, an OTP via SMS.

SCA exemptions worth knowing

• Low value — under 30 EUR, with a counter (5 exemptions or cumulative 100 EUR per card before forced challenge).
• TRA (Transaction Risk Analysis) — PSP/issuer with low fraud rates (under 13 bps for transactions up to 100 EUR; under 6 bps up to 250 EUR; under 1 bps up to 500 EUR) can skip SCA per transaction.
• MIT (Merchant Initiated Transactions) — recurring or saved-card charges where the cardholder gave initial SCA-authenticated consent.
• Trusted beneficiary — the cardholder whitelisted the merchant in their bank app.
• Fixed-amount subscriptions — first payment with SCA, subsequent equal-amount payments exempt.
• B2B corporate cards on lodged accounts (e.g. travel agency virtual cards) — separate exemption.

Liability shift

The big incentive to use 3DS2 properly: when a transaction is authenticated 3DS2 with ECI 05 or ECI 06, the liability for fraud-related chargebacks shifts to the issuer — the merchant is not financially liable on fraud reason codes. If you accept a transaction without 3DS2 (or with a failed authentication), the merchant carries the chargeback. Zunapro logs the ECI flag and 3DS2 protocol message on every order for dispute defence.

8. Open Banking France: DSP2, DSP3 and account-to-account

Open Banking in France is governed by DSP2 (the French acronym for PSD2) and now DSP3 / PSR, adopted in 2024–2025 and progressively in force through 2026–2027. The architecture is identical to the rest of the EU: licensed TPPs (Third Party Providers) access bank APIs to either initiate payments (PIS) or read account data (AIS), under explicit SCA consent from the user. The user benefit: pay directly from a bank account, no card, no card data leakage. The merchant benefit: lower cost (flat 0.05–0.30 EUR vs percentage), instant settlement (SEPA Instant), no chargeback exposure on most A2A transactions.

Major French PIS / AIS providers (2026)

SEPA Instant — the rail under PIS

Most French PIS transactions settle over SEPA Instant Credit Transfer (SCT Inst): 24/7/365, settlement under 10 seconds, up to 100,000 EUR per transaction, irrevocable on confirmation. Since the EU Instant Payments Regulation (entered into force January 2024, full mandatory acceptance by all PSPs by 9 January 2025 for receiving and 9 October 2025 for sending), every French bank must offer SCT Inst at the same price as a normal SEPA credit transfer — typically free for retail customers. This is the rail change that finally makes A2A viable at scale.

Verification of Payee (VoP)

Since 9 October 2025, every SEPA credit transfer (instant or standard) must include a real-time name + IBAN check ("verification of payee") before the payer confirms. This kills a major fraud vector ("authorised push payment" / impostor IBAN scams) but adds one API call to every PIS flow — make sure your PIS provider handles it transparently.

What DSP3 changes

• End of screen scraping — banks must provide a dedicated regulated API. Transition window through 2027, then scraping is illegal.
• Premium APIs — banks may charge for value-added endpoints (beyond regulated baseline).
• APP fraud liability — clearer rules on who pays when a buyer is tricked into authorising a fraudulent transfer.
• Wider data sharing under FIDA — Framework for Financial Data Access broadens beyond payment accounts (insurance, pensions, investments).
• Stricter MIT rules — merchant-initiated transactions need clearer customer-mandate paper trail.

9. B2B payments, invoicing, Factur-X and Chorus Pro

French B2B e-commerce is undergoing its biggest invoicing reform in decades. From 1 September 2026 every French B2B taxable seller must be able to receive structured electronic invoices (Factur-X format) via a Plateforme de Dématérialisation Partenaire (PDP) or the Portail Public de Facturation (PPF), and from 1 September 2027 small and medium businesses must be able to issue them as well. Large and mid-sized enterprises must issue from 1 September 2026.

Factur-X in 30 seconds

Factur-X is a French / German hybrid PDF/A-3 format with an embedded XML payload (the CII — Cross Industry Invoice — UN/CEFACT standard). For a human, it looks like a normal PDF invoice; for a machine, the XML is parsed automatically. Five "profiles" exist (Minimum, Basic WL, Basic, EN16931, Extended). For French B2B you typically issue the EN16931 profile (compliant with the European norm).

PDPs and PPF

The legal architecture has the State-run Portail Public de Facturation (PPF, operated by AIFE) acting as the central directory and free entry point, surrounded by private Plateformes de Dématérialisation Partenaires (PDPs) that handle issuing, receiving, format conversion and storage. As of 2026 there are 80+ PDP candidates accredited or in accreditation. Major ones used by SMBs: Pennylane, Sage, Cegid, Quadient, Generix, ESKER, Tenor, Sellsy.

B2B payment methods that survive 2026

Chorus Pro (public sector)

If you sell to French public entities (B2G), invoicing has been 100% electronic since 2020 via Chorus Pro. The 2026 Factur-X reform extends Chorus Pro logic to B2B. Zunapro auto-issues Factur-X invoices on marketplace orders, routes B2G to Chorus Pro and B2B to your chosen PDP.

10. Crypto payments and MiCA in France

Crypto payments are legal for French e-commerce — and the regulatory backdrop in 2026 is the clearest it has ever been. MiCA (Markets in Crypto-Assets Regulation, EU Regulation 2023/1114) entered full application at the end of 2024 and is now the harmonised framework for crypto-asset service providers (CASPs) across the EU. France was actually ahead of MiCA — the PSAN regime (Prestataire de Services sur Actifs Numériques) introduced by the loi PACTE in 2019 required registration and optional authorisation with the AMF in consultation with the ACPR. PSAN providers are now passporting under MiCA.

How a French merchant accepts crypto in practice

You do not hold crypto on your balance sheet (unless you choose to). You integrate a licensed CASP as a payment gateway — the buyer pays in BTC, ETH, USDC or a supported stablecoin, the CASP instantly converts to EUR at the spot rate and credits your fiat account, like any other PSP. Typical merchant integrations:

• BitPay — global, EU-passported, accepts BTC, ETH, XRP, USDC, USDT, fiat payouts daily.
• Coinbase Commerce — easy plug, popular with mid-market, on-chain settlement.
• Binance Pay — instant in-app payments for Binance's 200M+ user base.
• Coinhouse and Paymium — French CASPs, EUR fiat payout to a FR IBAN.
• Lyzi — Paris-based crypto-acceptance specialist for retail and e-commerce.

VAT treatment

The CJEU's Hedqvist ruling (case C-264/14, 2015) established that crypto-fiat conversions are VAT-exempt as a means of payment. For the merchant this means: the sale is taxed in EUR-equivalent at the moment of sale (you issue a normal TVA invoice in EUR), and any later crypto-FX appreciation is treated separately for income tax — not as additional turnover. Keep the EUR-equivalent recorded in your invoicing system; Zunapro does this automatically when crypto gateways are connected.

Travel Rule and TFR

Under the Transfer of Funds Regulation (TFR, EU Regulation 2023/1113), in force since end of 2024, CASPs must collect originator and beneficiary information on every crypto transfer above 1,000 EUR (and on all transfers if going to a self-hosted wallet). For merchants this is invisible — the CASP handles it — but it means the era of pseudonymous crypto checkout is over. Buyers expect KYC just like with cards.

All of this, one panel — Zunapro for French payments

The French payment stack has more moving parts than any other large EU market: CB + Visa + Mastercard cobranded, PayPal, Lydia, Apple Pay, Google Pay, four BNPLs, Open Banking PIS, SEPA Instant, Factur-X, MiCA crypto — and on top of that you sell on Amazon.fr, Cdiscount, Fnac-Darty, ManoMano, Veepee, Rakuten France, La Redoute and your own storefront. Reconciling one EUR balance, one TVA report and one dispute queue out of all that is a full-time job.

Zunapro is the orchestration layer. One connection to your PSP (Stripe France, Adyen, Worldline, Checkout, HiPay) becomes payments on every channel. Marketplace settlements (Amazon.fr, Cdiscount, Fnac-Darty, ManoMano, Rakuten) are imported, reconciled against orders, mapped to TVA buckets and rolled into a single ledger. Factur-X invoices auto-issue to your chosen PDP. Open Banking PIS plugs in for high-ticket. Chargeback evidence (3DS2 ECI, AVS, tracking, delivery proof) is attached automatically.

Frequently Asked Questions

Conclusion — France rewards the operators who do the homework

French e-commerce in 2026 is not the simplest payment market in Europe — but it is also one of the most rewarding for operators who learn the local stack. The combination of CB cobranded acceptance, mature 3DS2 SCA, a deeply rooted PayPal base, healthy BNPL diversity (Alma, Oney, Floa, Klarna), accelerating Open Banking under DSP3 and a clean MiCA-aligned crypto regime gives sellers more tools per checkout than almost any other EU country.

The merchants who win in France in 2026 do three things consistently. First, they make sure every transaction routes over the cheapest legal rail — CB for domestic, A2A for high ticket, BNPL where the basket profile fits. Second, they treat 3DS2 not as friction but as liability protection — challenge cleanly when needed, never accept non-authenticated transactions on risky baskets. Third, they consolidate the back office: one ledger, one TVA report, one PDP for Factur-X, one dispute queue — regardless of how many marketplaces and checkouts they operate. That is exactly what Zunapro was built for.
