Forget about sophisticated devices. Sometimes the best gadget is one you already have: Your own body.
The Daily Mail reports one Chinese student has been smuggling notes in during exams by writing them on her legs, as seen in photos her classmate posted on Chinese social media.
“I burst out laughing, literally. This is how my classmate cheats on her exams! Exams are never an easy test, right? Hahahaha, hope this post will make her famous!” captions the post, which has since gone viral.
