We've all done it: Parked and forgot to pay, then receive a hefty fine 2 weeks later. Most of us use parking apps and our vehicle registration number and personal details, including email and phone number, are stored in there. Parking management companies should check their database and send a text reminder to vehicle users (could be more than 1 per vehicle) who have not paid to promptly do so within 24 hours. Only if a customer does not pay within this time limit, can a parking management company proceed with issuing a Penalty Notice.
