This smartphone app is a general purpose barcode scanner with a minimalist interface. It uses the wildabeast BarcodeScanner plugin.
For the Digital Bitbox, it is also used to verify QR codes before signing a transaction. This avoids handcrafted man-in-the-middle attacks on compromised computers by verifying that you are signing the correct transaction.
Just click the button to scan. Plain text is printed as is. JSON-formatted text is pretty-printed. AES-256-CBC encrypted text is decrypted with a user-supplied password, which is set after clicking on the options icon at the bottom of the screen.
