Point of Sale.
The cashless society is irony because there is no cash left after all was stolen by corrupt government and with no electricity plastic money wont work.
EU is forcing us little by little to become cashless, electronic transactions have better traceability for tax purposes and all, i can speak of two examples:
I used to own a restaurant, 90% of the payments were plastic or check, the odd 10% came from drinks payed after the main bill was settled with card.
Another one: I lent my father 3000€ he paid me back in cash, when i got to the bank to deposit it they almost called the cops...
