It doesn’t work
After numerous attempts to start the payments, it had never been successful. Be honest it actually worked at certain locations, but many don’t. The charging workflow is not well thought, it’s almost silly: scan the 2d code, then go back your car to plug in the cable, then go back to the phone again to select charge time, then wait for the payment to go thru, oh, and there’s a 90 seconds limit to start otherwise you’ll have to restart. Come on, go out and check out what other vendors are doing. After 20-30mins trying, I give up.
