Neat tamper-evidence packaging concept: a random pattern of beads that's modified when you open the package, along with a smartphone app to automatically verify the pattern is correct.
Reusable glitter basically: to fake a seal, you need to make the significant effort of positioning each bead in the right place. Possible. But very time consuming.
I'd buy one!
@pete really clever
@nic It's actually not a new technique: I first heard about it for use in securing nuclear weapons.
@pete we're investors in DUST which does a similar thing at a much smaller scale with post-industrial diamond particles
@nic Too bad. Cellphone cameras would be a lot more convenient.
"@pete you need stronger optical sensors."
...also, after seeing just that message with #nocontext in my notifications, my first thought was "ah! a joke about my glasses!" 😂
@pete you need stronger optical sensors.
