The glitter nail polish is one of them. Maybe banknotes (from a high inflation currency) could work, if here as well you can safely publish the banknote number? | |

With USB devices, you might be able to simply tape over the connector, or (better) tape the cap to the body. But make sure an attacker can't slide wires past the tape to make contact. | |
| Mar 16, 2021 at 1:27 | comment | added | Solomon Slow | @EarlGrey, You're saying the tape has no value, but the people who make and sell it for profit know better. It comes down to how much one entity will spend to secure something, and how much some other will spend to defeat that security. That tape isn't highly secure, but it's cheap, and there is a class of snooper who will be deterred by it---Should the US military rely on that tape to know when it's time to change the nuclear codes? probably not. Should a business use it to discourage a courier from opening letters just on the off chance that they might find something good? Maybe so. | |
