I got a cheap USB #microscope to look at car paintwork, small electronics and the ratings label of some power supply units like mobile phone chargers, which are increasingly often way too small to read with bare eyes. I also happen to have a 365nm UV torch in my kit bag, so I thought I would look at some printouts from the office printer - here you can see the unique machine identifier code added to the printouts (these are very faint yellow dots) #security #privacy #opsec
