CB offers the ATM and EFTPOS networking infrastructure, while Carte Bleue is the debit card or mode of payment.

In an example of a genericized trademark, it is commonplace in France to refer to any payment card as a carte bleue, whether or not this is in fact the case.

The CB logo was initially designed in 1967 by the artist Jean-Marie Chourgnoz for the Carte Bleue group (acquired by Visa in 2010).

The CB logo, already widely recognized as it adorned the majority of bank cards (Carte Bleue being the most popular network in 1984), was then reused under license.

The gradient now features the colors of the French flag, while the letters have been slightly adjusted for better visibility from a distance.
