When I went to BlogHer last week in Chicago, I parked my car at SkyPark at SFO. As soon as I dropped off the car, I Scanaroo’d my car claim check and promptly ditched the paper one they gave me. When I got back and got on the bus after returning from the trip, the driver asked for the claim check. I brought it up on my phone, I showed him the claim check on Scanaroo, and he smiled and waved me on the bus. Early indications are good!
