Dekripsi PDF417 tanpa diminta

Apakah Anda memperhatikan informasi yang disandikan? Semua sentuhan tak berujung, QR, dan kode lainnya yang terjadi secara harfiah di setiap langkah. Barang di toko, tanda terima uang tunai, tanda dengan informasi untuk turis, tanda terima untuk tagihan listrik dan sebagainya.

Hari ini saya ingin berbicara tentang kode yang dapat dilihat secara teratur di bandara, atau lebih tepatnya - pada boarding pass. Pahlawan cerita ini adalah PDF417. Mari kita lihat apakah kode tersebut dapat didekripsi secara manual dan tanpa konfirmasi. Informasi apa yang perlu Anda miliki untuk ini? Berapa lama waktu yang dibutuhkan? Semua ini dan banyak lagi menanti Anda dalam publikasi ini. Ayo mulai!

Perhatian, di bawah cut - 30 gambar dengan ukuran total 16,3 MB.
