Validating prepaid airport parking barcode exit

[Zovannata]

I booked covered airport parking online, but when I scanned the confirmation QR code at the exit gate tonight, the terminal screen flashed an invalid scan error. The gate arm stayed down, and there are three cars honking behind me in line. How do drivers get the barrier raised without paying double?

Press the physical call assistance button mounted directly beneath the ticket slot to reach the on-duty facility dispatcher. Whenever automated optical scanners fail to read a mobile screen, an attendant using the ABM Parking phone number can locate your reservation record through your license plate number and manually trigger the exit gate. In case you are forced to insert a card to clear the lane, hold onto the paper timestamp receipt alongside your original booking email so you can submit an overcharge dispute the following morning.
