In a move that seems quite surprising, Citibank Australia has stopped taking notes and coins at their branches; data shows that less than 4% of their customers used cash at the branches and so to keep up with digital headwinds the bank has decided to go cashless; there has been a trend in Sweden and Iceland of cashless banks, but there has not been any worldwide trend in that direction; the bank will still keep ATMs going and teller services will also remain intact.
