This parking configuration requires the parker to pay for parking at the entrance of the parking lot. At the entrance of the lot is a parking meter which can accept coins, bills, smart cards or credit cards. The parker simply pays for the parking and the entrance barrier gate automatically opens. Once the vehicle passes the entrance closing loop, the barrier gate automatically closes. Typically, a daily rate or flat rate is charged. Hourly rates are not advised as there is no way to ensure the parker will stay for the time paid for. A pay-on-exit configuration should be used instead.

Next, the parker finds a parking spot. Once the parker is finished using the parking stall, the parker makes his/her way to the "free" exit. Once the parker's vehicle gets close to the exit gate, the exit gate will automatically open. Once the vehicle passes the exit closing loops, the barrier gate automatically closes.

Equipment required for this system: (2) barrier gates, (1) parking meter, Optional: protection posts, (4) vehicle loops, (4) vehicle detectors
