How many cards can be registered to 1 vehicle? What are the options for families (does the card have to stay in the car)?
There can be only one card per contract, so if a family wants to use several cards, they need to have that many contracts. Unfortunately, the aggregators don‘t allow for more cards per contract so far. One account can be shared by multiple family members, to authenticate charging sessions via app, with the RFID card in the vehicle as backup.
Can I use my MSP card for iV Charger?
Yes, you can.
Is the card necessary? Can we use just the app for authentication?
The card is necessary; many of the existing charging points are not yet compatible with the app.
