Over the last three years I’ve had a lot of folks ask me questions about using GrapheneOS. Let’s answer them!

    Exactly. A physical card is simply better in every single way. Imagine the stress when your phone inevitably dies, if you are out traveling and suddenly you have no access to money or communication. Screw that.

      I use Graphene. There is some banks that do tap-to-pay independent of Google Pay, but not mine. There is one legit good thing about modern tap-to-pay - it cycles card numbers, making it harder for retailers to track you.

        And using tap or chip on a regular credit card does as well. Every tap rotates through a set of keys in the card. The periodic use of the chip refreshes the tap keys. It isn’t the first gen tap to pay on credit cards anymore, it is much more robust.

        But beyond that, the retailer already saw your face when you walked in, already saw it at the point of sale, already tracked you as you traveled the store via WiFi, already saw the BT/WiFi profile of your rotating MAC address device as it only obfuscates, and in some cases, already had your phone join their WiFi network via EAP-SIM through your carrier, already scanned your license plate with Flock in the parking lot, and already saw your club/discount/points card number at the point of sale, so they already associated you with yourself.

        Tap-to-pay also sets up so all your transactions, on-phone or not, are captured by the handset manufacturer for further resale of metadata.

          Some of those might be less prevalent depending on where you are. But yes, there’s a lot of things to keep in mind.

          Also, the plastic card thing is neat, I did not know that.

          I’m especially annoyed about how easy it is to traci Bluetooth devices. I seem to remember that newer devices can rotate macs, but all my headphones are too old for that. And I kinda don’t want to throw away good hardware.
