we won't need cash or ATMs in the future we won't have to carry around bills and coins because we'll pay for everything with credit cards
at least we won't have all that change making holes in our pockets
everyone will use the same currency
it will definitely be easier money to transfer money between bank accounts in different countries and we won't have to change money when we go to on vacation to different countries that will be much more convenient
i think going shopping will be completely different from today there won't be any sales clerks and we'll pay for everything using special gadgets instead of cash there gadgets will use biometric information such as fingerprint or retina recognition to record our purchases...
everyone will shop online because we probably won't have the time to go shopping in regular stores then a lot of the stores will close down or there won't be any stores at all we'll order and pay for everything with e-money through our computers...
i don't think shopping in the future will be much fun the global economy will get worse and we'll have a smaller disposable income we'll only buy what is really necessary like food and clothes luckily i won't be here then so it won't be my problem...
