Comment intégrer Cartes Bancaires (CB) à mon Magento 2 ?

Cartes Bancaires (CB) is the French national card scheme — it co-badges with Visa or Mastercard on virtually every French-issued debit/credit card. Without CB acceptance, ~70% of French cards bounce at checkout because the bank routes domestic transactions through CB by default for lower fees.

To accept CB in Magento 2, you need a PSP that supports the CB scheme natively:

• Stripe FR — CB enabled by default for FR-region accounts. Easiest route, official Magento module.
• PayPlug — French PSP, CB-first. Free Magento module.
• Adyen — CB supported via the unified card form.
• Worldline / Ingenico (Atos / Sips) — legacy bank-direct route, used by big French retailers.
• Mollie / Lemonway — CB supported.

We configure the PSP, enable CB in the card-network selector, and verify with French test cards (4970 10... BIN ranges issued by BNP / SG / CA).
