Samsung’s (ssnlf) new smartphones may be able to test a user’s blood alcohol content while they’re having a chat on the phone, using a new stylus that has reportedly just been patented.
Citing a company official, the Korea Times reports that the S Pen stylus, an accessory that comes with Samsung’s Note series smartphones, can be used as a microphone for phone conversations while it is testing alcohol levels.
According to the Times, a Samsung official said the company applied for a patent last year and was recently approved by the U.S. Patent and Trademark Office. The official added, however, that new patents are not always put to use right away.
