Abstract
"SISTEMA DE VALIDAçãO DE TEMPO". Um sistema para validação de tempo compreende um terminal (1) com meios (7, 7') para sintonizar em um número de diferentes freq³ências de portadora (a-e), um dispositivo de autorização (6), por exemplo um cartão inteligente, capaz de se comunicar com o terminal (1) e meios (2, 5) para transmitir as estampas de tempo, utilizando um sinal modulado que tem uma freq³ência de portadora, para o terminal (1). O dispositivo de autorização (6) compreende um meio (8) para selecionar uma freq³ência de portadora para sintonizar para recuperar uma estampa de tempo. Um terminal (1) e um dispositivo de autorização (6) são fornecidos para utilização no sistema. Um programa de computador é adequado para carregamento em um dispositivo programável, por exemplo um cartão inteligente, para utilizá-lo como um dispositivo de autorização (6) para utilização em um tal sistema.
