Yes, supposedly anyone linked to your
MDE account can have their bands scanned. Now having said that, we recently returned from a 9 day trip at WDW using Memory Maker and atleast 50% of the photos were not showing up... especially our ride photos. Supposedly for the ride photos you don't have to scan your band at all, the photos are just automatically linked to your account. But just to be safe, MANY times we had our bands scanned for the ride photos and they still didn't show up in our account. I contacted customer support and emailed them the dates and times of our various Fastpass reservation times and they were able to find all but two ride photos I think. So take that info for what it's worth. Keep track of your FP times, you might need that info later.
