Give it back tyrone

Fuck off, Ahmed. You're not getting a bomb past the TSA by hacking the metal detectors.

Transmit strong signal and wait for "ring" of the tag.Effective jammers exist for rf,am and em systems,but they go from 500$ to 1200$.
Unusual systems,such as the ones made by Forsec and WG's sentinel,take a completely different approach and need custom jammers.

Have any of you even shoplifted? It's an exact science if you're good at it, and you really need retail experience and a decent head on your shoulders to be, but that's going beyond the point of this post. There are different types, but usually they send RF signals. The gates broadcast, the tags bounce back either a generic (RF tags) or a specific signal (RFID) tags. The former just tells them that you're walking out with something, while the latter can actually tell them what it was. The tags don't need a power source, because the radio waves provide sufficient energy to produce a signal.

Of course, all of that is for naught, since all that it takes to completely defeat retail security measures is a magnetic key (readily available online), a razor blade, a decent-looking professional outfit, and common sense. Every store has camera blind spots, and asset protection is in the process of being minimized as an avoidable operating expense, so...yeah. Shoplifting is much easier than it was in the '90s and early '00s.

Its very simple and can be summarised with the following formulae

d F = 0 , d *F = - *J, where * is Hodge star, F is the electromagnetic tensor, J is the 4 current.

They're pretty basic, actually, they just detect Melanin levels.

Give it back, Jamal.

Or you could just trigger it on somebody else, and move past when it's going off.

A few years ago I forgot to take the tag off my jacket, so when I walked out of a supermarket with a bunch of people, the guard simply stopped everyone and made each person walk through the detector on their own, while the exit was blocked for everyone else, until the situation was under control again.

They pick up on Midichlorian counts.

Oh wow. At Big W, Woolworths, Coles in Australia usually when I'm buying a whole lot of stuff. Or I go out with mum to buy her groceries. I will either forget to scan something or think its scanned. I walk past the detectors and it beeps. Mum and me just stand there. Looking around. No one comes to us. So usually we leave. This has happened to us like 4 times this year. Maybe I should scan all of the items.

fucking magnets, how do they work?
