Abstract

The present invention relates to an electronic card A including a magnetic stripe 2 and microprocessor 3 pair. The magnetic stripe 2 is scrambled at rest. This scrambling is broken only after identification by the microprocessor 3 of the code entered at the keyboard 1. This interruption of scrambling is timed by the microprocessor 3. The latter automatically invalidates the magnetic stripe 2 as soon as the card A is disconnected from a support. The scrambling becomes irreversible in the event of coding errors which are too close together in time. The card according to the invention is usable among other things for security applications of the plastic money type, for reserved accesses or various transactions.

Description

CARIE ELECTRONIQUE DE COMMANDE
CODAELE ET AUTO-VAI,IDA9LE
Dans le brevet principal N 85-09187 relatif à un dispositif de commande électronique utilisant une carte amovible à clavier et son support, il est fait état d'une piste magnétique solidaire de la carte, lisible par le support.ELECTRONIC CONTROL CARIES
CODAELE AND AUTO-VAI, IDA9LE
In main patent N 85-09187 relating to an electronic control device using a removable card with a keyboard and its support, reference is made to a magnetic track secured to the card, readable by the support.

la présente invention concerne une carte à clavier possédant un microprocesseur et-une piste magnétique, cette piste magnétique étant normalement brouillée, donc illisible, en configuration de repos.the present invention relates to a keyboard card having a microprocessor and a magnetic strip, this magnetic strip being normally scrambled, therefore illegible, in the rest configuration.

la figure 1 jointe représente la face recto de la carte.Figure 1 attached shows the front side of the card.

La figure 2 jointe représente la face verso de la carte.Figure 2 attached shows the back side of the card.

les repères indiqués sur ces figures se rattachent aux éléments suivants
- repère A - carte proprement dite
- repère 1 - clavier
- repère 2 - piste magnétique
- repère 3 - micro-processeur
L'autorisation de lecture s'analyse de la façon suivante quand la carte (A) ntest pas utilisée, la lecture de la piste magnétique (2) est automatiquement interdite par brouillage de cette dernière. Quand l'utilisateur légitime désire utiliser la carte (A), il doit d'abord composer sur le clavier (1) un code identique au code secret précédemment enregistré dans la mémoire associée au microprocesseur (3). la comparaison par le microprocesseur (3) entre le code composé au moyen du clavier (1) et le code en mémoire permet au microprocesseur (3), si les codes sont identiques, de supprimer temporairement le brouillage de la piste magnétique (2).La lecture de cette piste est ainsi rendue possible pendant un laps de temps défini à l'avance par le microprocesseur (3) à l'issue duquel le brouillage de la piste magnétique (2) réintervient automatiquement sous le contrôle du microprocesseur (3). En outre, dès la déconnexion de la carte (A) de son support, le brouillage de lecture de la piste magnétique (2) est rétabli automatiquement.the marks indicated in these figures relate to the following elements
- mark A - card itself
- item 1 - keyboard
- mark 2 - magnetic strip
- item 3 - microprocessor
The read authorization is analyzed as follows when the card (A) is not used, the reading of the magnetic strip (2) is automatically prohibited by jamming of the latter. When the legitimate user wishes to use the card (A), he must first dial on the keyboard (1) a code identical to the secret code previously recorded in the memory associated with the microprocessor (3). the comparison by the microprocessor (3) between the code composed by means of the keyboard (1) and the code in memory allows the microprocessor (3), if the codes are identical, to temporarily remove the interference from the magnetic strip (2). Reading of this track is thus made possible for a period of time defined in advance by the microprocessor (3) at the end of which the interference of the magnetic track (2) automatically re-occurs under the control of the microprocessor (3). In addition, as soon as the card (A) is disconnected from its support, the reading interference from the magnetic strip (2) is automatically restored.

Par mesure de sécurité, la lecture de la piste magnétique (2) est brouillée définitivement dès que plusieurs erreurs de manipulations successives ont été commises par l'utilisateur dans un laps de temps déterminé. Ce nombre d'erreurs ainsi que la durée du laps de temps sont déterminés par le microprocesseur (3) de la carte (A). As a safety measure, the reading of the magnetic strip (2) is permanently scrambled as soon as several successive handling errors have been made by the user within a determined period of time. This number of errors and the duration of the lapse of time are determined by the microprocessor (3) of the card (A).

Le code secret peut être introduit dans la mémoire associée au
microprecesseur (3) lors de la création de la carte (A) ou encore peut être
modifié dans le tenps par l'utilisateur légitime selon une procédure qui
intégre l'utilisation du code secret en vigueur à l'instant où cette
procédure va être employée.The secret code can be entered into the memory associated with the
microprocessor (3) when creating the card (A) or can be
modified in the tenps by the legitimate user according to a procedure which
integrate the use of the secret code in force at the time this
procedure will be used.

- la carte selon l'invention est utilisable dans des applications de sécurité
qui peuvent être dans le secteur de la monétique, de transactions
financières ou commerciales, d'accès à des zones protégées ou autres. - the card according to the invention can be used in security applications
who may be in the electronic banking sector, transactions
financial or commercial, access to protected or other areas.
