It bothers me that this always has a cord hanging from it. If I can charge it and process payments remotely, it shouldn't have the cord permanently attached. That should be removable. I bought the docking station so I could have it sit on a tabletop, rather than having the square reader just sitting out. It makes it look kind of official until you see the cord going to nowhere. It doesn't need to be plugged in to work, only for charging, so the cord should come off.
