So now the BBC article is the one that seems to have launched this whole day's reporting. And it's a little closer to what Alex is kind of talking about. The headline of the piece is, quote, will travel be safer by 2022. This is an article by the aforementioned Lena Zeldovich, who doesn't write exclusively about spying toilets. This is a discussion about emerging technologies that could help facilitate travel in the near future, an industry that's been hit particularly hard by COVID-19. She discusses a breakthrough in breathalyzer-type technology that's been created by Gabby Sarussi of the Ben-Gurion University in Israel. Apparently, his breathalyzer has shown a 92% accuracy rate, so it may be fairly close to being up for consideration as a means to be able to control the spread of the virus while still allowing safer, less restricted travel. One of the other technologies that's discussed is the vaccine record tattoos that have been researched by folks at MIT, and that technology has received funding from Bill and Melinda Gates. That research. Nothing in this article says you'll need a vaccine tattoo in order to travel in the future. This article honestly is just Zeldovich's perspective on what could be coming in terms of travel.
