The tags don’t know where they are or what you’re doing.
Imagine you’ve got a cute little animal that whistles, except when it’s wet. The animal is blind, deaf, and can’t really feel anything except that it’s wet. It doesn’t know if you’re moving it somewhere in your purse or just walking it out the door.
But at the door, there’s another critter that’s really good at hearing cute little animals that whistle. And if you try to walk one past it, it squawks very loudly.
It’s kind of like that, except security tags aren’t disabled by getting wet, they’re disabled by magnetism. And they don’t whistle, but they emit radio waves. They don’t know where they are or what you’re doing with them, but if one of them is emitting the particular security radio waves when you’re walking through the door, the door alarm goes off in response.
