Yes, but not nearly as many of them at one time. Your typical door frame is roughly 7′ x 3′ = 21 square feet of opening for all those little critters to get through when the door is open. But with this new segmented door, it looks like only 40% of it is usually open at any time when someone passes through it. That means 60% of those critters that try to enter the room when the door is open will still bump into the door instead. Of course, most of the remaining 40% will just bump into the person instead, but could still get through if they cling to that person as s/he’s coming through.

That said, it seems to me that the security function that IDs specific people would be a much more useful feature for most people and businesses.
