Flocks aren't reported to have any capability to track wifi/Bluetooth. Leonardo cameras are though. As always, best to leave your phone off, in a faraday bag or at home when doing illegal things. Reading your CC data over nfc is just silly. Even if it had the hardware equipped you'd have to be up on the pole dry humping the thing for it to power the chip through your pocket.

I advocate for fighting state surveillance, but let's not get carried away with hyperbole or we end up sounding like the "5g lets bill gates lobotomize you remotely" crowd.
