It does appear to be a 'battery compartment' door on the bottom of the back side of the reader.
In the photo of every color stacked, you can see a Mini-USB port and headphone jack on the bottom.
In the 360 view you can see four discrete buttons on the left edge, a bi-directional rocker button on the right edge and an omni-directional switch on the face. The SD slot either has to be on the top or in the 'battery compartment', but I can't find an image of the top.
An online user manual would help sales by answering some of these questions.
