Chacun à son goût. I admit that many people I know don't carry cash anymore, or only carry a small amount "for emergencies".

I haven't touched a note or a coin for 6 months now, last time I just had to because the machine only accepted coins

Only at places like farmers markets for me, and even then, I'd say at least half of vendors accept credit cards. And frankly I hate using cash. I don't want to carry physical money around when tapping my phone is so easy.
