NFC Phone As A Key

[skidoofast]

I’m torn , on one hand I want relatively no tech, on the other I want to use my cell phone as a key to operate the vehicle if they have an app or remote door locks and remote start (remote heat and cooling)

Not need the key to drive

I started a thread about that. No info yet on those phone features or whether or not there will be a subscription for them. Also I have that NFC feature now. Helpful if I run out to the car for something and forgot my key but have my phone. Annoying if you don’t want to carry the key at all. I have to hold the phone to the door handle to open the car and put it in the center console and leave it there while driving.

I'm not super familiar with the way other cars use the phone app to verify ownership of your vehicle when locking and unlocking, but this thread has me thinking that using some form of 2FA tied to the NFC radio on phones could be a FOSS means to authenticate ownership through phones. An app like Aegis but tailored for cars would be super in the case of Slate.

Biggest problem is that this could be a vulnerability and make it easier to steal. If it requires tapping a button on the screen rather than doing it automatically it could mitigate this.

Heres a good article describing BMWs ultra wide band (UWB) digital keys and how they work. Technically, its not NFC, bluetooth, or wifi.

Edit to clarify that first gen digital keys are NFC and require you to tap the handle with the phone. The new UWB keys detect your proximity and unlock as you approach.
