Who the fuck uses cash lol. I do keep a 20 inside my phone case for emergencies though.

I have a mini card holder that sticks to the back of my phone case (MagSafe) if I'm going somewhere I'll need health care card. Such occasions are extremely rare though, it's just doctor or dental visits

Also if I'm driving somewhere then you gotta bring the car papers with you so my license just lives in the same case as them.

Passport also has its own case/bag if I need to bring it with me for something
