If it’s a multi-family home system, why not just use contactless badges/fobs to identify each family? When you move in you sign the contract, give your bank details and get a fob. Then just badge with the fob to charge

The only EVs I've used are the hire-from-the-street ones available in some cities in Europe. There's generally a small credit (free minutes) if you leave them charging at the end of a trip. There are RFID tags in the car to activate the charger — I assume it's essentially equivalent to a company credit card used to buy petrol, or when you hire an ICE car with fuel included and there's a special credit card in the glovebox to use to pay for the petrol.
