In the future, coins and cash will not be used for commerce processes among populations, as a result, all payments will be made by credit cards only. I partly agree and think that it is a quite comfortable to carry everywhere, however, it will impact folks by using its out-of-control.
Initially, I believe that bank cards provide the safe transportation of any amount of money. If someone wants to buy an expensive property such as an apartment, a car, a country house, the person can make instantly the remote transaction through credit cards linked to a bank account worldwide. For instance, when tourists go to travel to foreign countries, they mainly make payments for large and small purchases by charge cards, followed by, almost every shopping center in developed nations has terminals installed for the convenience of guests. Thus, the advantages of using a cards outweigh the advantages of using cash in the future.
Secondly, there is the other hand. People use it out of their control leading to bad debts. They cannot afford to pay interests, in addition, they cannot enter the system to transit money as a result of forgetting their password and even the account will be locked. For example, we have many cases like these in Vietnam, population waste tons of money to buy something they do not really want in the retail market and lost money from the unauthority access system of the bank. Therefore, these are potencial risks in the future.
To sum up, community use bank cards in all case. It is useful and convinient. However, it has ability high risk in payment methods.
