A portable device (11) for performing secure transactions with transaction terminals (12), including first means (111, 113) for performing a secure transaction using first transaction resources stored in a first memory (114), and means (115) for contactless communication with said transaction terminals. The device includes means (116) for interfacing with a smart card (13) including second means (131, 133) for performing a secure transaction, and means (117) for selecting one of the first secure transaction means and the second secure transaction means, with particular reference to data on the presence and validity of said card, whereby a transaction may be performed either by the portable device (11) or by said smart card (13). In either case, data communication with said transaction terminals (12) is provided by said contactless communication means (115).

L'invention concerne un dispositif portatif (11) destiné à effectuer des transactions sécurisées avec des terminaux de transaction (12), comprenant des premiers moyens (111, 113) permettant la réalisation d'une transaction sécurisée, à partir de premières ressources de transactions stockées dans une première mémoire (114), et des moyens (115) de communication sans contact avec lesdits terminaux de transaction. Selon l'invention, le dispositif comprend des moyens (116) de dialogue avec une carte (13) à micro-circuits comprenant des seconds moyens (131, 133) permettant la réalisation d'une transaction sécurisée, et des moyens (117) de sélection entre lesdits premiers moyens de transaction sécurisée et lesdits seconds moyens de transaction sécurisée, tenant compte notamment d'informations représentatives de la présence et de la validité de ladite carte, de façon qu'une transaction puisse être réalisée soit par ledit dispositif portatif (11), soit par ladite carte à micro- circuits (13), l'échange de données avec lesdits terminaux de transaction (12) étant dans les deux cas assuré par lesdits moyens (115) de communication sans conctact.
