Thinking out loud. The chip in my pants

Yesterday my wife sent for Whatsapp video. The video is very interesting in view of the fact that there is shown a chip sewn into the pants factory method.

Man in all seriousness proves that we're being watched by satellite. Maybe he believes it.
My wife immediately began to check the newly purchased jeans, and there I found exactly the same chip.
It all worked out).

Only there is one caveat. It's not the chip. It's just a sticker from the theft that would the product "rattled" at the exit of the store.

It is about these stickers and when it was said Zadornov. Supposedly cunning immigrants from ex-Soviet countries, in American stores just tore off the sticker and steal the goods, quietly passing through the frame.

Here I have a question. Why are these jeans not "rang" when we came out of the boutique?

Or frame is not configured and is purely for show, or sticker not work?
By the way if you bought a product and at the checkout it was removed this thing from theft, which is now hanging on all the goods , and the frame output "rings", you know. The cashier forgot to remove the sticker.

Of course it can be glued, for example, to the child and let run through the frame back and forth until the guard will not bother.)

But probably better to remove and throw out like yesterday did my wife.
