The use of paper money
has been eliminated from the world and is no longer accepted anywhere. Credit cards and online shopping are the best ways to pay for needed things. There are only 6 exchange rates, one for each major continent (Antarctica does not have one).This has made things a lot simpler for most of the people on the planet. Older people have a hard time adjusting to the new technology, and it will of course take time to get used to. For the most part, it is well liked and was a good idea.
