Visited on October 1st and charged with Shell RFID, no issue.
There are no directions to the chargers inside the parking. It's on the entrance level, in the north corner.
The signage regarding opening hours is confusing. There's a sign saying it closes 30min after the store. But on the payment machine there's a day and night tariff.
I didn't check if the charger kiosk still worked, I doubt it. In the past there used to be contactless payment here, but those were killed when Shell took over, if they weren't already broken before.
