What Happened?
Express Pay does not support multiple active parking sessions simultaneously across all Express Pay locations.
If a driver already has an open Express Pay session at another location, they cannot start a new one until the existing session is closed.
In this situation:
- The driver was allowed to enter because their license plate was recognized as an enrolled Express Pay user.
- However, the system blocked the new session because a previous session is still open.
The driver will receive a text message notification informing them that their Express Pay session could not start.
Common Causes
Existing Open Express Pay Session
The driver previously parked at another Express Pay location and their session did not properly close.
Because the session remains open, the system blocks any new Express Pay session until the previous one is cleared.
Multiple Vehicles Entered Under the Same Express Pay Account
Express Pay accounts may have multiple vehicles associated with them, but only one active Express Pay session can run at a time.
If two vehicles linked to the same account attempt to enter Express Pay locations at the same time, the first vehicle will successfully start a session, and the second will receive a message that the session could not start.
Required Actions
If the issue is caused by an open session, contact Flash Support to invalidate the Express Pay session.
Provide Support with the following information:
Parker license plate number or phone number
Flash Support will invalidate the open session, allowing a new Express Pay session to begin.
Recommended Resolution for Shared Vehicles
If multiple drivers are using vehicles under the same ParkWhiz account, advise each driver to create their own ParkWhiz account using their personal mobile number.
