Descriptografar PDF417 sem avisos

Você presta atenção às informações codificadas? Todos esses toques sem fim, QRs e outros códigos que ocorrem literalmente a cada passo. Mercadorias em lojas, recibos de dinheiro, placas com informações para turistas, recibos de contas de serviços públicos e assim por diante.

Hoje eu quero falar sobre um código que possa ser visto regularmente nos aeroportos, ou mais precisamente - nos cartões de embarque. O herói desta história é PDF417. Vamos ver se esse código pode ser descriptografado manualmente e sem avisos. Que informações você precisa ter para isso? Quanto tempo vai demorar? Tudo isso e muito mais esperam por você nesta publicação. Vamos começar!

Atenção, abaixo do corte - 30 imagens com tamanho total de 16,3 MB.
