PARKSHIELD — PARKING APP CHECKLIST 1. Use the operator named on the current sign, not an app used nearby before. 2. Confirm the vehicle registration, location code, start time, duration and price. 3. Save the confirmation where you can retrieve it later. 4. Do not store passwords or full payment-card details in notes. PARKSHIELD organises the journey and provider hand-over; it does not claim to replace every parking operator.
