Direct answer: License-plate billing in a parking facility means the vehicle is logged at entry with its plate and a timestamp; at exit the plate is read again, the elapsed time is converted into a fee based on tariff rules, and it is collected via POS, HGS toll balance, or mobile payment. The barrier opens automatically once payment is confirmed; no physical ticket or card is needed.
Entry and exit flow
At entry, the plate seen by the camera is read automatically and logged in the system along with the entry time. When the same plate is read again at exit, the system finds the entry record and calculates the elapsed time; this duration is converted into a fee according to a predefined tariff table.
How are tariff rules set up?
Tariffs are typically defined from the panel using rules such as hourly bands, a free first X minutes, day/night differences, or a daily cap. A different tariff can be temporarily activated during campaign periods or special days.
Payment integration
The calculated fee can be collected via the POS device at the exit, the HGS toll balance, or a mobile payment app. Once payment confirmation reaches the system, the barrier opens automatically; if an exit is attempted without payment, the system can alert the attendant or the vehicle owner.
Subscription and guest management
Subscriber vehicles on the whitelist pass for free or at a discount according to a defined rule; a separate fee/contract logic can be run for these vehicles. Time-limited or one-time authorization can be defined for guest vehicles, while blacklisted vehicles are blocked at entry or exit.
