Hola a todos, de alguna lugar encontré este código para usarlo con Arduino uno en el proyecto de un Cierre para puerta a travez de un relay, el mismo me esta funcionando perfectamente hasta que le trato de agregar una segunda llave, cuando le agrego mas de una abre el relay con cualquiera hago, adjunto les dejo el Código para ver si me pudieran ayudar a corregirlo, gracias a todos. Nota: El código de tarjeta le puse 12345.

unsigned char flagDone; // goes low when data is currently being captured
