## License Plate Backfill
Members imported through [interim imports](/data-import/interim-import) may have an RFID tag but no license plate on file,
depending on the import data. Turn on **License Plate Backfill** to let FlexWash read the plate from the
LPR camera photo on the member's next wash and automatically update the vehicle record if a plate is missing.
