I like to go running with nothing on me besides a house key, and it's useful to be able to stop by Whole Foods after the run and buy a snack without a phone, watch, or wallet.
A powered door lock and keypad and you won't even need the house key!
Wear an NFC ring on your finger.
Unlike your palmprint, you can get a new ring with a new private key if yours is compromised.
I've consciously reduced my pocket contents from car keys+wallet+phone to driver's license+phone. I'd love to be able to get rid of the phone sometimes.
