I knew about this. I simply wanted something that already is accepted in most places, but also isn’t PayPal but can still create virtual cards for payment. Even if they were to be leaked, no harm done because they’re virtual and probably only had the exact amount of money it needed to complete a purchase (once). So it has 0 at the time of a leak or is probably removed.

Any clever “google Dork” ways in finding these “flock” devices through eg Shodan?

Some phones, even if they are turned off, still send telemetry data.

I use GrapheneOS and for safety reasons, when I know I won’t get a call, or if I have to travel somewhere discreet, I’ll use one :P Works well for me!
