CB, French payment system
CB, a card payment system, is the leader in France with more than 10 billion transactions per year. The system is managed by the Groupement des Cartes Bancaires CB.



Trust in the CB card is based on security. To ensure it, the CB card must have the best security systems, which must constantly evolve along with the sophistication of fraud.


CB also takes care to preserve a balance between security and ease of use. Security must not reduce the ease of use of the payment system that is preferred by the French.


  • Since 1992, the CB card has been fitted with a chip. This key security element checks for each payment the confidential code entered by the cardholder and performs security checks.
  • Since 2002, CB cards have been fitted with a chip to the new international standard EMV.
  • Since 2005, an additional encryption system, DDA (Dynamic Data Authentication), has been added to "third generation" cards, which generates a unique signature for each transaction, calculated from random data, and so enhancing the security of payments.

These elements contribute to making the CB card one of the safest means of payment in the world.

Security that is constantly improving 


Improvement of the security of payments by CB card is continuous work. 


Your next CB card will be even more secure than the current one, which is itself more secure than the previous one. 


Prevention and the fight against fraud are the ongoing principles driving CB to constantly improve preventive security systems, whether they are for cardsterminals or remote payments


Of course, this does not discharge users from following a few elementary precautionary rules.
