Have a phone case that holds my DL and 3 cards just fine. Stopped carrying an actual wallet long ago. Was just using a card sleeve. Then moved to a
Bellroy Slim Sleeve. Now just use the iPhone case since I always have my phone with me anyway.
Did about the same thing with keys. Can get in house with code, work replaced keys with credit card size ID badges, etc. So now only carry the key for the car I am driving.
