Here's the list of devices supported by fprint
For non -standalone readers, you'll have to look up the actual fingerprint reader embedded within it.
Edit: it looks like this is a Bluetooth keyboard. My guess is it's highly unlikely to work with Linux as a fingerprint reader.
Same here. Fuck the naysayers who say cold turkey or nothing. Do what works for you.
For OP: One caveat to the vape plan is you'll likely need to get a vape that's refillable so you can customize the nicotine level. Juul/vuse/disposables typically only come in one, or at best, 2 nicotine levels, which prevents effective tapering.
Also, don't fall into the trap of vaping places you wouldn't have smoked (e.g. in your house/car). That can increase your nicotine dependency.
Good luck!
