Earlier quoted context omitted.
As someone who lived two years in Germany a) That's a good joke. From faster to slower: NFC > PIN > signature > cash. b) You should look into the real cost of dealing with cash. EC is stupidly cheap since it's basically the cost of a SEPA direct payment (we're talking 1-2 cents per transaction). Debit card payments can also be pretty cheap in Europe. All those annoying restaurants and small shops that take only cash…
Sorry, but what is "EC" and "SEPA", and what do they have to do with the real cost of dealing with cash?
SEPA is the Single European Payments Area, standardizing how to process fast and cheap payments, all transfers are in Euro, from 2018 on also having a standardized API between banks, wire transfers are free or below 1 cent each, etc.
