Thumb bandits were nefarious individuals prevalent in 2015. They stole people's thumbs "after amputating" (most notably, those of hospital patients), according to the Newsline column on the front page of the October 22, 2015 issue of USA Today, in order to gain access to high security or high clearance areas via the use of thumb pads, and then committed their crimes — usually burglary.
- Thankfully, there aren't any real-life thumb bandits and even if this was the case, the severed thumbs would be quite useless to them because the fingerprint scanner on something like an iPhone, for example, will not work with a thumb — or any other digit for that matter — that has been amputated from a living body.
