I'm a minimalist when it comes to crap in my pockets.
Garmin FR230 with RFID stuck to the back for opening doors at work.
iPhone 7
Minimalist wallet (

Single key to my FRS with no keychain
Wedding ring
I enter and exit my home through the garage and can open and close my garage door from my watch when I come and go from runs.
I would love to ditch the key and wallet and use the phone or watch for everything. The auto industry makes too much money on $400 keys to go with some universal system for unlocking/starting cars from a phone. I'm also a bit annoyed that although Google and Apple both use the same industry standard NFC payment system, the two can't coexist at some retailers, not for technical reasons but due to being paid off to accept one over the other even though at the cash register they are 100% identical.
