How do I know if there is a pinhole camera in my handbag?

This matter can only be known by personal inspection ...

You can't tell anything from the appearance.

Only when you pick up the handbag and check it inside and out can you know whether there is that thing ...

At the same time, you should also pay attention to the behavior of the person holding the handbag ... If he just carries the bag normally, it should be no problem. If he behaves strangely, there must be something wrong with him ...
