For short-term parking, the system reads the In-vehicle Unit (IU) numbers of vehicles entering the car park. Your CashCard must be inserted in the IU for parking charges to be deducted when leaving the car park.
For season parking holders, the system identifies the vehicles through their IU numbers, when entering and leaving the car park.
Most EPS car parks give a 10-minute grace period. You will not be charged if you exit the car park within 10 minutes.
