No one is, because the cashless society isn't happening. The concept of abandoning cash is at this stage merely a thought experiment. Even in Sweden, the most significant action taken in that direction is a discussion about whether to have a discussion, from the government.
But why would any government abandon cash? Any fiat currency needs at least some cash to go around, otherwise the remaining cash exchanges that still happens, a lot of which are untracked, would be outside of the control that governments still have over them; valuation. If you take away their cash, they will simply find another bartering tool.
