Unless I'm explicitly buying something with cash, I'm almost always in the state of no cash, but with my phone.
The last time I had cash on my person, it was because I was traveling, and wanted some on hand. I haven't carried cash, as a rule, in almost a decade.
I'm not in the valley, but I have the opposite policy: I systematically use cash unless it is not possible to do so. (It's better for privacy.)
I have your policy, but for a different reason: I generally don't want the merchant to be charged a fee for the transaction.
Totally valid reason. I use cards for the sake of ease of tracking and protections offered by cards. I wish there were an optimal situation wherein you had privacy and protection both.
Yep, here in NZ I never have cash and make electronic payments for everything (even $1 convenience transactions).
