Carte Bleue was a major debit card payment system operating in France. Unlike Visa Electron or Maestro debit cards, Carte Bleue transactions worked without requiring authorization from the cardholder's bank. In many situations, the card worked like a credit card but without fees for the cardholder. The system has now been integrated into a wider scheme called CB or carte bancaire. All Carte Bleue cards were part of CB, but not all CB cards were Carte Bleue.
