Yes, as long as your bands are linked it should work. I was there last week and we split up and my hubby scanned his band for ride photos that showed up in my account. Also, my sister was using a photopass card because she didnt have MBs and all I had to do was add the photopass number to my account and it downloaded the pics from her card.
I didn't entirely trust the system so I stopped by the photopass place and scanned each band to be sure. At the end of the week, we all had the 239 photos on each one.
