A first telephone is connected by means of a telephone line via a line switch to a remote telephone by way of another telephone line. The user of the first telephone dials the number of the remote telephone and enters his account information. The prompter prompts the entry of the Personal Identification Number (PIN), and then all of the information is processed by the CPU and the PIN memory. Upon the completion of a successful transaction or when prompted by the 24 hour reset circuit, the PIN modifier circuit alters the appropriate PIN in the PIN memory.

Un premier téléphone (1) est connecté au moyen d'une ligne téléphonique (3) via un commutateur (5) de lignes à un autre téléphone (9), qui est distant du premier, au moyen d'une autre ligne téléphonique (7). L'utilisateur du premier téléphone (1) compose le numéro du téléphone distant (9) et entre ses informations de comptes. Le programme interrogateur (24) demande l'entrée du numéro d'identification personnel (NIP) puis toutes les informations sont traitées par le processeur central (17) et la mémoire (21) de NIP. A la fin d'une transaction réussie ou sur demande du circuit de réinitialisation 24 heures (33), le circuit (27) modifiant les NIP change le NIP approprié dans la mémoire (21) de NIP.
