Well, the moment of truth is that people will possibly embrace that particular situation but what makes them stop is the capability of their country and of the individuals. Besides, this is not hard to learn and I know everyone can do it but unfortunately, they are in such desperation due to the lack of support from the government and materials to run the system which gives courage as well.
Yet, I won't disclose the chance to be in the adaption as I literally will come but it takes longer, many years to come before it was realized.
That is correct and it would be needing translation in the regional and the local languages as well.
Also - it is not possible in the near future because it needs smart phone, internet connection and obviously people who are educated enough to understand the procedure.
I would say that translation would be easy step, that shouldn't really be a problem because they will handle it and it would be done within a few days, quite easy step. However, the fact that smart phones can't be used by many elderlies is still a problem, and I am not sure that we would be able to neither, like when we reach 80+ would we be able to, even though we grew up with smart phones?
I think there needs to be a back up, because if all else fails, cash is till there and we are doing that anyway. All in all, the only thing you would save in this situation would be trees, because they wouldn't be used to make paper money, aside from that most other things would be the same.
Do you think a lot of trees will be saved if we stop using paper money? Taking into consideration, that new money are not printed every day. And compare it to an amount of useless data printed on regular A4 paper daily.
I have tried many times to stop using cash, but over and over again I have returned to using coins. There are so many businesses around the world that require coins, that makes me think we will never start living cashless. There are so many units that accept coins, that it will cost enormous amounts to convert unit payment system to cards.
