Cashless society makes transactions more faster and many people are comfortable in sending payment through online by using their phones and cards because it is much convenient to use than standing and falling in line just to pay bills and buying things. I think there are still some people in sweden will still be using cash in 2023 because there are poor people who can't afford buying a phones and cards, so i think cash will still exist in sweden in 2023 and in other countries if that happen.
