It is available in many cities and parking lots, but not all parking lots support the app. Before using it, it is recommended to find out in the app whether your city or parking lot supports its service. If the parking lot supports it, you can find the corresponding parking lot number in the app and complete the payment.

The app itself is free, but there may be additional service charges or handling charges when paying with it at certain parking lots. These fees may vary depending on the policies of the parking lot. Before choosing a parking lot and paying, it is recommended to check the parking lot policy for possible additional charges.
