Cash is physical money, like coins and paper bills, that people use to buy goods and services. It is one of the oldest forms of currency and is accepted almost everywhere. Cash is easy to carry and can be used instantly without needing any technology, making it a convenient option for everyday transactions. Many people prefer using cash because it helps them manage their spending better. When you pay with cash, you can see how much you have left, which can prevent overspending. However, with the rise of digital payments and credit cards, cash usage has declined in some places, but it remains an important part of the economy.
