Seems weird. The fact it talks about rolls of film and reading DX codes suggests that it's able to scan undeveloped film. Maybe that's possible, but I've never heard of that before.
If it only scans developed film, then it's unlikely to still be in the cannister with DX codes, and I've never seen that film delivered to a customer in a roll - it's normally cut up into strips so they can be stored flat.
