Does cashless society discriminate against the poor and elderly? (2019)
I think there almost needs to be a "Reacher Law", in that there should be minimal friction to participating in society aside from maybe cash and an ID. 
I definitely find a default assumption of having a smartphone that's creeping in everywhere (android / iOS compatible & has an active data plan) to be increasingly cloying.Currently, all I can do is politely decline and insist that I neither have the Play nor Apple store; I still find it uncomfortable even giving away my phone number.
I couldn't even get into my gym the other day, since they'd transitioned to app sign-in only (phasing out barcode tags); I'm forced to beg the attendant to look me up by phone number every time.*EDIT: I hope ranting about smartphones in a cashless-ness thread isn't too off topic
