The customer service links are all for bluetooth connected devices, and the question here is about USB connected devices (which Intuit doesn't seem to actually offer but they won't admit it).  Magtek card swiper connected DIRECTLY with USB will work (you can't go through a USB hub, has to have one cord directly connected the swiper and the desktop)  I keep looking but haven't found a chip reader that connects with USB for desktop use, and the swiper doesn't work on an increasing number of newer card styles unfortunately.
