La présente invention concerne un procédé permettant d'effectuer une transaction, comprenant la réception d'un pseudo-numéro de compte qui correspond à un numéro de compte bancaire. Ce pseudo-numéro de compte peut être reçu par un dispositif sans fil portable et peut être généré par un ordinateur serveur à distance. Le dispositif sans fil portable peut recevoir le pseudo-numéro de compte par le biais d'un premier réseau et le fournir à un dispositif d'accès. Les dispositifs d'accès comprennent, généralement, un lecteur pouvant recevoir le pseudo-numéro de compte et, par la suite, envoyer un message pour demander une autorisation pour une transaction. Le message de demande d'autorisation peut comprendre le pseudo-numéro de compte et est envoyé à un réseau de traitement des paiements. Le message de demande d'autorisation est envoyé au réseau de traitement des paiements par le biais d'un second réseau. Le réseau de traitement des paiements peut ensuite traiter le message d'autorisation et renvoyer une réponse indiquant si la transaction est autorisée ou non.
