This is just something I want to make sure that I understand regarding the setting:
Evenyone has a SIN, unless they are SINless. And everyone's SIN is entered in their Comlink, is that correct? And the SIN and Comlink are all conected to their Credstick, right?
You walk around with your Comlink on and your Augmented Reality goggles or whatever on, and the environment knows you're there. So as you walk past, for example, a Subway you will see an Augmented Reality Jerod holding your favorite sub (based the last purchase that Credstick made) and he''s be all "Eat Fresh, extra mayo just how you like it!" at you.
Also Lonestar can drive down the street with a scanner, and anyone with an arrest warrent will pop up with a big red arow over their head. Not to mention the hackers who will screw with your Comlink just because they can.
So if you didn't want all that you could just turn your Comlink off. Two problems, though. First a lot of gear has to go through your Comlink into the Matrix for you to get the maximum benifit. Second, in a high law area walking around with your Comlink off is reasonable suspicion for you to be detained and searched.
Now to avoid hackers & getting IDed on the street, and still be able to be on the Matrix, is there a way to turn your Comlink's broadcast sigal off so you're active but others can't see you? But that would still leave you open to being stoped & searched.
So could you but a second Comlink to use as a Honey Pot and load that bugger up with all kinds of anti-intrusion 'ware?
