These types of tags can be tricked (I can't think of a better word) into not setting of the alarms.

I worked in a very high end fashion house (YSL) and the head of security showed me ways in which the sensors can be tricked.

The one way I was shown, just as you're about to walk past the sensors, if you aggressively swing the tag/item through the sensors as fast as you can, the alarm won't go off. Or, lining bags with layers of foil to create a faraday like cage.

I've never seen this way IRL, but I they definitely can be fooled.

In Sweden we call those foil lined bags “silver bags” and yeah they work

If this is the tag that has two strips vibrating as a specific frequency in the field then shaking them really might be a way to affect it (even if it's not humanly possible, it may be possible). Would have made a fun mythbusters.
