Abstract

Momentaneamente direcionada para cheques, e que se vale de uma propriedade da impressão dos talões, motivada por resolução do Banco Central do Brasil, que determina que o cheque deve conservar os necessários requisitos de segurança, tais como papel indelével e fundo artístico. Para atender as exigências acima, as empresas que imprimem os documentos de segurança, como, por exemplo, as folhas de cheques, imprimem na camada de fundo e de modo imperceptível as palavras 'nulo' ou 'anulado', ou qualquer outra palavra/inscrição com o mesmo objetivo, de tal modo que não interfira no conteúdo visível do cheque a ponto de invalidá-lo, mas que possa ser observado de alguma maneira quando esse documento sofrer algum tipo de agressão quimica com o intuito de alterar o conteúdo do mesmo; onde se emprega uma caneta elou um dispositivo especial como dispositivo de aferição, capaz de tornar visível a mencionada camada escrita de modo imperceptível, onde uma certa quantidade de produto seja liberado pela mencionada caneta/dispositivo, onde o seu evanescimento corresponda com o destacamento das referidas palavras, anteriormente impressas de modo imperceptível."METHOD AND DEVICE FOR AFFECTING DOCUMENT AUTHENTICITY".
