more or less the use of digital cash has becoming popular nowadays especially to the people living in the city and to the teenagers. China has even a vending machine that serves drinks or instant foods by just scanning the QR code and paying it using an application

The telecommunication companies in my country have made a digital money where you give them the money and in turn they give you the money in your mobile wallet with which you can transfer to others and even transfer fee money from your bank to your mobile wallet.

Digital money is not the cashless society, because the physical currency gets a digital form. Here the currency is backed by gold and other sources. Cryptocurrency can be termed to be cashless society, because the backing is purely on technology and there is no need of a physical form.

Gradually the entire world is now shifting to the cashless system; not only in China. Even in Africa where most communities lacks internet facilities, they still manage  to reduce carrying bulky money by introducing mobile money system by almost all the communication networks, where the individual can send and receive digital money without necessarily having a smart phone. Again, the e-zwich, debit and credit cards have been fairly understood by many due to safety and faster transactions.
Bitcoin is can also be seen as a digital money and would no time be transacted worldwide

I don't think we should rely on physical money anymore. This should be changed. For a better greener world we should avoid paper money. Digital currency must won in near future.

And It scares me though, seeing most of the people really sooner that relying on technology alarms me. If there would be a cashless society there would be a possible centre strorage of all the possible account that may produce in that given time and it can be possible that if you will abide the rule they will use all the profit that you have for them to control you, and I guess thats not a good Idea and how about the third world countries? And less fortunate people, they will be isole if that will happened.

Cashless society does sound convenient but the negative side is Credit Card fees and Bitcoin fees. I like the alt coins that have the lowest fees which is the first step towards a cashless society.

In a Cashless society services and commodities are exchanged for other commodities and services. so any change in the exchange rate of these services can be viewed as increase in value of one commodity or services and decrease in the value of another. so this can be interpreted as inflation with respect to a commodity and deflation with respect to another commodity. alternatively in a cashless society services and commodities can be exchanged for a common commodity such as gold. in this case gold can be viewed as a currency and any increase in prices relative to gold can be viewed as inflation.

Well in our country, bitcoin is not that popular and so does the method of payment online. We still highly depend on fiat money because we are not that advance in terms on technology. I think the use of digital money greatly depends on the state of technology of a country and if the country has a low economic standard, it will ban bitcoin and any other form of digital money.
