Safety first: No high‑voltage work is needed for RFID checks.

Test with known‑good card: Use an original Polestar‑supplied RFID card to rule out incompatible tags.
Clean reader area: Wipe the RFID reader window with a soft, dry cloth to remove dirt or film.
Scan position: Hold the card flat against the marked area and wait a few seconds. Try different orientations.
Module check: If recognition remains unreliable, the RFID reader module or antenna may be failing and should be replaced.

RFID cards or tags are not recognized, but the charger otherwise works when set to ‘open’ mode.
