Even the us is super cumbersome. They should just support ApplePay, Google Pay and a credit card and be done with it. Remembering the password for some finicky app just makes the quick fill up too much trouble. Even better would be if the car had secure handshake so once you’ve registered once for a network, you can just plug in and be done.

Do the charger standards pass any data? Like could you plug in, the car identifies itself as whatever VIN (add whatever anti-tampering challenge-response you want to armchair-design), and the electrons just start flowing?

  That's how the Tesla chargers work. It also looks like CHAdeMO has a 'Plug and Charge' protocol defined: https://www.chademo.com/chademo-releases-the-latest-version-of-the-protocol-enabling-up-to-400kw/ https://www.chademo.com/chademo-releases-the-latest-version-... But that's pretty new, and not the SAE standard used in the US. So, it'll be a while...

I know ChargePoint stations in the US accept standard tap-and-pay, so are compatible with Google/Apple Pay.

  This is how the Tesla superchargers work - authorization and billing is all in-car and takes place automatically, so all you do is plug in and it immediately begins charging. For other charging networks, however, it seems to be needlessly more complicated.

Even the us is super cumbersome. I just present my RFID Chargepoint card, and it pretty much just works.

  With cash, what happens if I put in $5 and my car only uses $3 of electricity? Or if someone pulls out the charge cable after my car's only taken $1 of electricity? With electronic payments, you can pre-authorize a reasonable amount, then charge the customer for the amount they've used - no excess charges or change required.

      Which is the attendant or cashier gives me change. I haven’t seen a human attendant near any charge point stations.

    Wait, have you never paid cash at a gas station before? You go up to the teller, tell him which pump your car is in, and get your $2 back.

      Or if you buy a ticket for cash at a train station from a vending machine, it gives you back change usually in dollar coins.
