A credit card system (100) is provided which has the added feature of providing additional limited-use credit card numbers (126) and/or cards. These numbers and/or cards can be used for a single transaction, thereby reducing the potential for fraudulent reuse of these numbers and/or cards. The credit card system finds application to "card remote" transactions such as by phone or Internet (112). Additionally, when a single use credit card is used for "card present" transactions, so called "skimming" fraud is eliminated. Various other features enhance the credit card system which will allow secure trade with the use of elaborate encryption techniques.

L'invention concerne un système (100) de carte de crédit présentant une caractéristique supplémentaire d'addition de numéros (126) de carte de crédit et/ou de cartes à usage limité. Ces numéros et/ou cartes peuvent être utilisés pour une seule transaction réduisant ainsi le potentiel de réutilisation frauduleuse de ces numéros et/ou cartes. Le système de carte de crédit trouve une application dans les transactions "carte à distance" telles que par téléphone ou par l'internet (112). De plus, lorsqu'une carte de crédit à usage unique est utilisée pour des transactions "carte présente", la fraude dite d'"écrémage" est éliminée. Diverses autres caractéristiques améliorent le système de carte de crédit, ce qui permet de sécuriser les échanges à l'aide de techniques de chiffrement élaborées.
