Abstract

Se describe un método y aparato para el suministro y utilización de una tarjeta de llamada telefónica. En un ejemplo, un cuerpo plano incluye un sistema de memoria, un generador de múltiples frecuencias de tono doble (DTMF) y un altavoz. El sistema de memoria es configurado para almacenar los datos de identificación que permiten que el usuario establezca una llamada telefónica. El generador DTMF es conectado con el sistema de memoria y es configurado para crear los tonos DTMF protegidos por coritraseña para transmitir los datos de identificación. El altavoz es conectado con el generador DTMF y es configurado para emitir los tonos DTMF. Los tonos DTMF podrían ser reproducidos en un teléfono para realizar una llamada utilizando el aparato de tarjeta de llamada telefónica. Debido a que los datos de identificación son reproducidos en el teléfono y son protegidos por contraseña en lugar de ser ingresados en forma manual por el usuario, los datos de identificación son menos susceptibles al revelado no autorizado y de esta manera, son menos susceptibles al uso fraudulento.
