I used Evie card (used to be free) in Evie and ChargeFox. I just add the same card /card number in each app and it used to work on both system. I am not sure if it has changed in last 1-2 months. I sold my car so can’t test.If you folks are likely to need to use chargefox chargers and you want an RFID card as a backup to the app it might be a good idea to order one soon.
It costs about $10 but can take up to 30 days to get to you.
Just a suggestion
I ordered 2 EVIE card, registered those in both app(chargefox and evie), kept one in car and one in wallet. It was a good combo and was free!
Btw, any day I will pick Evie over ChargeFox. I have driven around 36k km in 1 year and charged in ChargeFox, Evie, AmpCharge, BP Pulse and Tesla Supercharger. Chargefox was the worst one and offers ton of pain!! With LFP batteries Tesla supercharger is the best due to preconditioning!
