Sweden, a counntry in the EU, did this in 2012.
Then they introduced a (small) fee.
Apparently Norway's Vipps is free for small amounts, but charges 1% for large.
Too tempting for the EU not to play, but that will replace a duopoly with a monopoly, which will end up doing what monopolies have always done. "For the greater good" here is to incentivize competition.
