"Сashless" Сashless saves time. You can pay for a trip to the subway without standing in line. There will not be a lot of coins in your pocket. If you use some cards, you can return some of the money - Cashback. Using the cards you can safety your money. For example, if someone has stolen a purse, you can block cards. In case someone tries to withdraw funds, then a message will come, by which you can understand that the card has disappeared. If we move to a fully cashless settlement, we will be faced with difficulties. For example, if there are problems with the Internet, you will not be able to pay for the purchase. In small towns there is not always a connection, etc.
