If I had to guess? It's SpotHero that's sharing their database. I recently used a reservation in a Chicago garage and the gate went up as soon as I pulled up to the ticket machine, before I could scan my barcode. I talked to an attendant to make sure my parking was valid, he said the license plate (which you also register with SpotHero) triggered the gate opening, not the barcode. The garage at 2600 Western is a SpotHero client.
