While I find your implants path very interesting, impressive and Cyberpunk worthy, I would’t use any externally accessible keys / fobs / etc myself. I wouldn’t want someone to unlock my stuff while I’m sleeping. Same reason I avoid face detection unlock. My mind is the best safe out there, I can memorize a very lengthy passphrase and have no problems typing it.
Instead of my ID, I submitted a picture of dolphins and the text “So long and thanks for all the fish!”. And never came back.
