This is a prototype. The billing will be added later, when it is deployed for real.

That is the same with billing at public charging stations for electric vehicles. In the past, you basically got the charge free of charge. The billing, if there was any, was more about the parking. That was to encourage to build up a charging network.

But now, new charging stations are regulated by the calibration rules, like every by law calibrated weighing device you find in shops. That means they now measure the charge and this will be billed. The requirements are strict, because everything as to be reliably recorded, so the proof would stand in court. That makes those systems expansive. That means electric charging at public stations seems to be more expansive than fueling your ICE.
