Abstract
EN UN PROCEDIMIENTO Y UNA DISPOSICION DE CIRCUITO PARA LA REALIZACION DE PROCEDIMIENTO DE DESVALORIZACION DE UN TARJETA DE DEBITO SE UTILIZA LA MEMORIA COMO CONTADOR DE ETAPAS MULTIPLES. CADA ETAPA DE CONTADOR ESTA COORDINADA CON UN BIT DE UNA MEMORIA DE CONTROL. PARA EVITAR MANIPULACIONES DE LA TARJETA, SE HA PREVISTO LEER ANTES DEL REGISTRO DE UNA SUMA ANTERIOR Y LA DESCARGA DE LA ETAPA DE CONTADOR DE VALOR INFERIOR DEL BIT DE TRANSMISION Y DEL BIT DE CONTROL CON DIFERENTES UMBRALES DE VALORACION. UN CIRCUITO DE ESTE TIPO ES REALIZABLE EN ALTA SEGURIDAD CONTRA MANIPULACIONES CON PEQUEÑO COSTE DE CIRCUITO.
