How do I prevent neighbors from using my charging point?

Your charging station gets its own QR code: anyone who wants to charge scans it and pays in advance before any power is supplied. Without scanning and paying, the station simply remains off, even for neighbours or unknown cars. This manages access automatically, without you having to check who is connecting. Note: this does not prevent someone from physically grabbing the cable or entering your property; a physical measure may be needed for that. Even if the station is only for your own use, or if the problem is actually about household power, this is not the right solution.
