The Cartes Bancaires (CB) logo, the French card payment system, is a pair of large white letters “C” and “B” in a custom graphic style on a rectangular badge. The “C” is a rounded shape with a horizontal cut through the middle, while the “B” is built from two wide rounded “capsules” split by the same horizontal line, making both letters read as one solid mark. The badge background is a diagonal gradient from blue through white to red—the colors of the French tricolor—with a thin white outline framing the mark.
Cartes Bancaires (CB) is France’s national payment system and acceptance network for card and mobile payments, created in 1984 and used by banks and financial institutions for cashless transactions within France. Its operation is coordinated by the Groupement des Cartes Bancaires CB (GIE CB): the organization sets the system’s rules and standards, ensures interbank interoperability, and drives the development of security and payment-acceptance technologies, which is why the CB mark is widely seen on cards, payment pages, and terminals in France. For payments outside the country, CB-branded cards are often issued as co-badged products with international payment networks, so the familiar “domestic” CB infrastructure works in France while international acceptance is available abroad.
