    I live in New York City. The current way to pay for buses and subways is with a Metrocard. You can buy them at some stores and check cashing places, or at most subway stations. You can pay with cash or a card. Now, at great cost, they are introducing a ‘better’ system where you pay for your rides with a credit card or smart device. They are planning on getting completely rid of the Metrocards. Soon, they will be able to trace anyone’s movements.

      There’s literally a GPS enabled mind control device in almost everyone’s pocket.

        Yes but its not required to get around, airplane mode, and not everyone has their cell service tied to their name, etc.

        This same lame comment gets posted on every fucking internet post about Privacy. Stop it.

        Not everyone uses a compromised phone with the GPS turned on all the time. Plenty of us put in effort to mitigate cell phone tracking, and anyone can leave their phone at home to completely eliminate tracking where they go.

        FYI there are a number of privacy-focused Android distributions, and lots of options on Apple iOS to disable what can track you. Stop being complacent and protect your own privacy instead of hand-waving away the entire premise of Privacy.

          If your cell phone is turned on, the phone company knows where you are. This fact is why your GPS doesn’t take 5 minutes to show your location every time you turn on your phone. The OS gets the cell towers to identify where you are and combines that with GPS to get a quicker lock and more accurate location.

          The most secure Android OS cannot turn that off. If you transmit or receive data to a cell phone network, your location is known.

            Sure, there’s no way around that, even dumb phones are triangulated by default and that data is sold.

            But doing just that is better than being triangulated AND leaking your GPS data to every Tom Dick and Harry that asks your phone.

              EDIT: Sorry, I am idiot. What I described IS triangulation.

              Reeeeeee! Phones. Are. Not. Triangulated.

              Most cell towers use phased antenna array, so they know relative direction all the time. And distance can be estimated from latency and signal strength.

              Two cell towers allow to get precise location from angles. Angles are derived from phase differences on elements of array and can’t be manipulated like latency or signal strength.

                But using two cell towers and angles would literally be triangulation…

                    What do you think the cell towers are triangulating and forming angles with? The person’s phone is the third point in the triangle. You only need two other points to triangulate something’s position.

                  Sorry, I am idiot. What I described IS triangulation. Alternative with distances is trilateration.

            No that’s not very accurate. Cell phone tower triangulation only gives a rough approximation of location, and GPS is definitely able to be disabled by the software. I know a bit about these things as someone who has compiled their own android ROM from open source. I’ve been working on this stuff for more than a decade now.

            Regardless of all of the above, anyone can turn off their cell phone or choose to not carry it to eliminate the ability for that cell phone to provide location data on them. This alone negates all the stupid “gotcha” comments about trying to preserve one’s privacy while owning a smartphone. So we are back to my first comment on this topic, with the point of STOP IT.

              That’s why I said they send that to allow the phone’s GPS to get a lock quicker and more accurate. All cell phone towers have GPS. Agps means the tower sends its GPS constellation to the phone so it doesn’t take 5 minutes to lock.

              https://en.m.wikipedia.org/wiki/Assisted_GNSS

              So yes, even with GPS disabled, the phone company has a rough idea where you are.

              If you are in the city on high band 5g, that location is known within 15 to 600 meters.

            The GPS thing is different. The phone downloads the satellite positions from the net instead of having to receive the same data, very slowly, from the satellites themselves.

          You only know what you’re told. There’s all kinds of space inside your phone for components with capabilities you know nothing about.

        Yeah and there’s a reason you can’t drive unregistered and that reason has nothing to do with bad drivers.

      Take off the tinfoil hat, NYC is not planning to get rid of metrocards. The credit card payment ability is just a convenience feature to get more people riding transit.

        I mean, my tinfoil hat is on for the same reason - I haven’t been arsed using Transport for London’s Oyster card because there’s a cost cap placed on all travel paid for by one single card. I suppose my bank has my details already so it’d better that than having another party with my data… and another card to lose, more likely.

      You can buy preloaded credit cards with cash from convenience stores. It’s as trackable as your MetroCard.
