Nowadays, people rarely keep large amounts of money in their pockets. What is more, plastic cards have attracted so many business people and ordinary citizens that it just stopped to pay off to deal with normal money in form of cash. it is much more convenient just to have a card and visit the banking machine once in a while. A plastic card takes much less space in the wallet and is just more comfortable to be used. The same goes for the recently famous certificates for gold bullion and stuff like that ownerships. Those certificates just prove that you are the owner of this and that amount of gold bullion or whatever and in this way the gold bullion can stay in the bank, safely lying in the strongbox and all you end up with is a piece of paper with a confirmation on it. that you are the owner of that and you are entitled to collect the money for it anytime you want. That is what people tend to do nowadays. Besides, there are also many more handicaps serving us in other branches. The entire internet in fact is there just to make our lives easier! Our parents and grandparents did not have such luxuries and they still had to deal with all the problems and they somehow managed to handle everything without any problems that would be worth mentioning.
