So, we are moving into a new era where Fiat currencies are getting some competition from Crypto currencies and multiple other payment methods. People are simply not interested in using cash anymore, because cashless payment options are more efficient and also more convenient. < Debit & Credit cards / Crypto currencies / Gift cards / E-Wallets / Cheque / PayPal etc. >
So with the endless alternative payment options available, cash payments are slowly being replaced by more practical and convenient payment options.
Is there still a need for Cash in this evolving world?
I can think of several scenarios where Fiat currencies are still needed, namely :
1. Where there are no electricity infrastructure.
There are remote locations that doesn't have electricity, but these days through the advancement it is possible as solar energy can be produced even from very low sunlight.
2. Where it is not safe to carry expensive smart phones.
As mobile operators have developed inbuilt wallets, we can enrich the security so that even if smartphones were stolen or taken by someone else they can't make use of it.
3. Where there are no access to the Internet.
More firms were trying hard to give cryptocurrencies physical appearance. This is hard, and paper wallet is the only way it can be viewed physically. Some form of offline transactions were made, but at some point it needs connectivity to register to the block.
4. Where there are a high number of illiterate people.
This is not at all a problem, people found difficult to use phones. Now everyone who haven't gone for school uses it better than a techie. So, being illetrate is not a big issue with cryptocurrency.
5. Where there are people with disabilities that presents challenges for electronic payment options.
People moved from physical cash to card payments, and this gets effective when governments promote it and encourage using card/other forms of digital transactions for all the needs. One such promotion is taking place through out Japan.
