It has been widely noted that happiness is very important to our life. However, what is happiness? It seems difficult to define, for different people have different ideas. Some people are brought up that most important thing in their life. They obtain happiness from seeking fame and profit. Other people are in pursuit of mental edification. They serve people heart and soul and find happiness from it. | However, notes and coins have been around for thousands of years because of their many advantages. One outstanding characteristic of cash is that it is very fast. There is no waiting for the transaction to take place. Furthermore cash is a universal language. Illiterate people can use it, and the best currencies can be used anywhere in the world. A third point is that cash does not require a highly developed infrastructure to support it. There is no need for telephone lines, internet connections, credit card reader machines, or other devices in an economy that depends on paper notes. This makes cash a very practical solution in poorer countries, where the bulk of the world’s population lives. A big advantage of cash is that the spender is able to spend only as much as he or she has. Contrast this with credit cards, where the user may spend far more than he or she has, and can even end up in debt. Some people expect that we will soon pay for everything from a microchip embedded in our hand or in an ID card, but there are many people who oppose such concentration of information in one source, and who prefer the anonymity of cash transactions.
