The card includes a light-up indicator and a piezoelectric buzzer, which indicate that the code entered through the keyboard into the card coincides with the code previously recorded using the encoding console in a memory of the card, thus verifying the authorization of use by the carrier of same. The encoding console includes magnetic tape reading heads and recording/reading of messages of the status and user code in the card, an alphanumeric keyboard for entering the code and a display which exhibits messages regarding the status of the card and assigned code, and a printing head of the said code.
