A cashless economy refers to a system where financial transactions are conducted digitally rather than with physical currency. Several countries have moved significantly towards cashless systems in recent decades as electronic banking and digital payment methods like credit cards, debit cards, and mobile wallets have grown in popularity. While a cashless system provides benefits like convenience, transparency, and security, it also presents disadvantages like privacy concerns, technological dependence, and the risk of hacking or fraud. Many governments and central banks are actively promoting policies to further encourage cashless transactions.
