No shit, Sherlock? In the UK a lot of fuel pumps have credit/debit card readers built in, and if not cards are accepted everywhere for payment already. But yes electric charging companies here are still wierd about accepting such standardised payments, and we did just introduce a new law about it [0] promising "most" but not all chargers will accept cards.
