When I’m out I keep my phone on airplane mode and in a little faraday bag. I am not dragging out my phone and waiting for it to reacquire signal every time I want to buy cigarettes. Nevermind that defeats the point of the faraday bag…
Your phone does not need an internet connection to tap to pay, in the same way your credit cards do not need an internet connection to tap to pay
How do you do tap-to-pay from inside a faraday bag?
I was addressing the “waiting to acquire signal” part, not the “removing from a bag” part which I imagine to be fast
The phone is already trying to connect to cell networks when it’s in the bag, the moment it comes out it’s already broadcasting which means the cell networks can triangulate your location even before ‘signal is acquired’.
I just wrap the Faraday bag around the card reader and let NFC do its thing. The cashiers hate me, but sometimes the cute ones get confused and let me draw them in their underwear.
