Paper money is disappearing, thankfully, we do have the technology and capability to create more secure and paperless transactions, also crime would go down in an alarming rate, another type of criminals would rise too but anyways the entire world could be a safer place
I don't think it's disappearing, still paper money is very useful in this world and it will never happen that it will disappear.
The trend is online transaction but it's good to see we are given different options so can transaction online and offline and this will serve people
with different purpose.
