Visited today without charging.
There's no gate, the charger is among the parcmeter spots outside the stores. Meaning it must be accessible around the clock.
There are no parking instructions specific to the charger, so the same price as the other parking spots must apply. There's half an hour of free parking, must register at the parking meter. The prices apply from 06h00 to 01h00, so unless you come charging in the middle of the night you would have to pay for going over half an hour 🤔
The credit card reader seems to work. There's an option for credit card on the screen and the reader activates when selecting that option. The screen shows prices "DC: 59ct/kWh+10ct/min, AC: 45ct/kWh+3ct/min". There are no AC connectors here so the AC price is irrelevant. It's much cheaper than the price when scanning the QR code which is currently 81ct/kWh+6ct/min.
