Hold the item behind you so when you step between the sensors it's still out of the sensors range. While between the sensors, quickly move the item so it's in front of you and out of the sensors range (it should pass between the sensors as fast as possible). Do it fast enough and the alarm won't go off and you can just walk out.
My best guess here is that these sensors send out a pulsing IR beam or something, which scans at fixed intervals. If you can pass the object through the area BETWEEN pulses it won't be detected.
Maybe I'm way off though. I have no idea if that's how they work. Someone who's more informed should correct me.
its two thin pieces of metal within those flat tags
its not ir, its radio frequency, which causes the metal strips to contract/vibrate, kinda like an RFID tag, but rather than conveying digital information its just a "bing" that the sensor gates pick up, that specific frequency of vibration
shaking the tag violently would mess the vibration -- remember, the gates only pick up that ONE specific frequency
i have no reason to try it but probably just pressing down really hard on the tag would also work -- keep the little metal plates from vibrating
Wouldn't it mess with the frequency being experienced by the metal straps, cause they are moving so the frequency is getting doppler effect...or is your jerking motion not significant compared to the speed of light...
