@aamurusko79 This was done on an xtool as well. Not mine sadly, I don't think its in the price range I'm willing to pay for it. But so far it seems to be a really nice machine.

@Aknorals Actually, that was the first thing we tried. At some point we where able to scan it. But it 'expired'.

Oh, and the smell of burned banana peel also wears of after 12 hours. So there's that...

You where all thinking it. And the answer is 'yes!'. Yes you can totally LASER engrave a banana to exfiltrate data from your secured premises. Just out of the machine the text is barely noticable. But the next morning? Clear as day.
