Abstract

La invención se refiere a una tarjeta con chip con al menos dos dispositivos de bobina (2,3) para transmitir sin contacto así como, en su caso, con contactos (1) que permite transmitir por contacto datos y/o energía a un dispositivo de lectura/escritura (terminal). Una de las bobinas (2) del primer dispositivo de bobina (2) se destina al campo cercano, la otra bobina (3) al campo alejado. Un dispositivo electrónico realiza la diferencia entre las diferentes bobinas (2,3) en función de las diferentes características físicas, como la fase y/o la frecuencia y/o la amplitud y/o la energía. Una primera parte (4) del dispositivo electrónico (6) genera una señal estéreo (S1), que toma un primer valor característico (A1) cuando las bobinas de campo lejano (3) y el campo cercano (2) se encuentran simultáneamente en un campo alterno electromagnético y la alimentación por la bobina de campo lejano es suficiente. Las diferencias de campo alterno electromagnético entre las bobinas de campo lejano (3) yde campo cercano (2) se utilizan en forma de diferencias de fase alterno y/o de frecuencia y/o de amplitud y/o de energía para generar un segundo valor característico (A2) de la señal estéreo. Cuando las diferencias de campo alterno magnético entre las bobinas de campo lejano (3) y de campo cercano (2) desaparecen, la señal estéreo (S1) está ausente o toma un tercer valor (A3); en los dos casos, la tarjeta con chip co su entorno permanece utilizable con funciones limitadas como la energía producida por la bobina de campo lejano (3) lo permite. Cuando la señal estéreo (S1) toma el segundo valor (A2), la tarjeta puede por el contrario utilizarse con funciones suplementarias que van más allá de las funciones limitadas, de manera a ejecutar diferentes funciones utilizando totalmente el efecto estéreo según su funcionamiento en campo cercano o lejano.
