I pay exclusively by card, by myself if it is possible for me. I also allow myself to believe, to have my opinion, that the reluctance to accept payment cards and electronic payment is primarily motivated by the fact that it is not possible to subsequently manipulate the figures of plowing and profit. The margin for payments has long been included in the price, so merchants do not incur any increase in operation and payments to banks, everything has long been pre-paid just by making the purchase. The only way to defend yourself is to boycott merchants where electronic payment or card payments cannot be made. However, abolishing cash as such would create a new, far more colossal problem, banks could use so-called negative interest to guard our money, and the state would have an overview of how much money anyone has (if there were no banknotes) and everything would only be in accounts… But such we don’t have to be afraid of the scenario, because the first ones who would reject this idea are our politicians, it would spoil their business… I believe that payment by cash, card or electronically is fair, it should be ordered by the state!
