You can use NFC off your phone to initiate the charge at EA stations I think. Same as Chargepoint.
I will have to try that at the next EA. But the big hassle is simply turning my SmartPhone on as I always keep it off and it takes a while to boot up.
I think from now on, if I know my next stop will be an EA charge station, I will just leave it on until I get there.
I have plenty of cards for the other machines and that's the best way of them all, IMO. I keep a CP card with my bike keys and another in my wallet (as well has have several others) as CP is what I use the most these days. Such as at Cisco Grove, CA, about midway between my houses.
