Abstract

L'invention concerne un système de transaction téléphonique comprenant un dispositif de transaction (10) et une interface téléphonique (11). Le dispositif de transaction est composé d'un moyen mémoire dans lequel les informations relatives à la transaction sont stockées. Le dispositif de transaction comprend également un moyen permettant de sélectionner les informations de transaction stockées devant être transmises à l'interface téléphonique, et un moyen de transmission permettant de transmettre les informations de transaction sélectionnées. Le dispositif de transaction convertit les informations de transaction en une chaîne de numérotation appropriée qui informe l'interface téléphonique quant à la séquence et à la durée d'un signal devant être envoyé. La chaîne de numérotation doit être transmises à l'interface téléphonique à l'endroit où elle est mise à exécution. L'interface téléphonique comprend un récepteur (12) permettant de recevoir les signaux provenant du dispositif de transaction, un moyen de traitement (13) connecté en circuit au récepteur qui convertit la chaîne de numérotation produite à distance en un signal compatible avec un téléphone.
