Abstract

resumo “sistema e método de implementação de comunicação de campo próximo”. são divulgados um método e um sistema para implementar a comunicação de campo próximo (nfc). o método inclui: modular um sinal digital para gerar um sinal de áudio e executar o sinal de áudio modulado com um dispositivo de transmissão; e realizar amostragem do sinal de áudio e demodular a amostra do sinal de áudio para obter o sinal digital por um dispositivo receptor. a presente divulgação é capaz de implementar nfc entre dispositivos de comunicação móvel que não são equipados com chips de nfc, resolvendo assim os problemas de requerimentos de hardware que utilizam esquemas do padrão ntc são maiores, e variações de aplicação atual são limitadas.
