The only time I was asked for ID was when I didn't have the actual DDE card, just the letter saying I would be getting one. This was last spring, shortly after they opened the card up to AP'ers and not just FL residents, and apparently they were inundated with requests and it took a long time to get the actual card. Once I had the actual card, I was never asked for ID or the AP. I don't think the card holder would be asked for the AP, because at the time I ordered mine, I asked if my expiration would still be a year since my AP would not be active for the full year and I was told the DDE card was valid for a year from when it was purchased, regardless of AP expiration, I just needed the valid AP to be eligible to purchase the card. I used the DDE for two trips with the AP and thought that would be it, but I ended up planning another trip for my DD's birthday since she was off school a few days. I will be using the DDE card for this trip in two weeks, but my AP expired in November.
