...well that would certainly take away it's price advantage from using an SD / usb sick. Nevertheless, as the posts piled up, the tech does seem a bit more valid if all you want to do is encrypt data before long-term storage. However, in any other circumstance, I'd choose a different solution.
oh absolutely, the 2d scanners we use are about 400 dollars a pop.
I'd argue a USB version is MORE secure as the attacker would have to know what they are looking for. Any key logger would pickup the output of a bar-code reader; and that sort of output would obvious when reviewing your catch.
you're assuming all barcode scanners use a wedge method and output the data as keystrokes instead of raw data on a com port. protip: usually, and especially in this case, you'd have it as raw data on a com port, thus, not capturable with "any keylogger"
The pixels of the 2D code are 2mm by 2mm (0.08 inch x 0.08 inch) and there is about two-fold redundancy in the encoding. Reconstructing should be possible even when there are destructive creases.
This. Where i work he have several dozen 2D barcode scanners and even more Zebra Z4 and Z6 type printers. on a ZM400 we had a bad head, and a good deal of the barcode was completely absent from the word go, however operators were still able to correctly scan the mangled codes with 100% accuracy.
