QR code – um código de matriz introduzido há mais de dez anos pela Denso-Wave Corporation (Japão), que inicialmente era usado apenas na indústria automotiva, mas sua utilidade foi rapidamente apreciada em outras indústrias. Um código de barras nada mais é do que uma etiqueta óptica que contém informações sobre um objeto, e a leitura ocorre com dispositivos especiais, no nosso caso, uma câmera de um dispositivo móvel. O Código de Resposta Rápida se parece com um arranjo aleatório de pequenos quadrados pretos em um fundo branco.
Esse código de barras bidimensional é encontrado em todos os lugares da vida moderna – em shopping centers em embalagens de produtos, nas páginas de publicações impressas e em recursos da Internet. Usando as informações criptografadas em um código QR, uma pessoa pode acessar rapidamente um recurso específico, cujo link está escrito no código, ler um e-mail, mensagem de texto, descobrir as coordenadas e assim por diante. Na maioria dos smartphones e tablets modernos, um programa que lê o código de barras está presente no sistema por padrão. Mas a conveniência e a funcionalidade de tais utilitários não atendem a todos os usuários.
Nesses casos, o software alternativo vem em socorro, então o utilitário QR & O Barcode Scanner permitirá que você leia com rapidez e precisão qualquer código de barras que permitirá, por exemplo, conectar-se automaticamente a uma rede Wi-Fi, acessar um URL, ler um número exclusivo de uma edição de livro ( International Standard Book Number) , e veja todas as informações sobre o produto selecionado. Existem funções úteis no programa como ligar o flash, foco automático, inverter o código de barras, visualizar todo o histórico de varredura.
