There are many ways that you can protect your flash drives from being used by others. There are ones that even go so far as using voice recognition. However, seeing as this is the day and age of technology, things can be hacked and bypassed if it is the right person.
This is the very reason that the Top Secret Custom Made USB was created. Instead of being password protected, needing fingerprints or something of that nature, this uses a wax seal to prove its legitimacy. If the seal is broken, someone has been looking where they shouldn’t have been. The immediate reaction I had to seeing this was obviously confusion. Pouring hot wax onto a flash drive does not sound like such a swell idea. That is why this drive has been fashioned out of porcelain, so it will hold said seal. You can choose from a variety of colors for the wax, such as bordeux red, orange, blue, pink, and green. There is also the option of 2, 4, and 8GB sticks. They all come with a fancy stamp with a letter of your choosing, and cost somewhere around $46.
