A:Answer To respond literally to your question, then yes, the Bower Case will hold several XQD cards inside. As I understand the XQD format's form factor to be in between an SD and a CF in size. Since the CF format is slightly larger and the case supports 4 of the CF devices via indents than your cards will be kept safe warm and dry inside. If you are asking if this particular Bower Case has an INDENT for the XQD format, then I will have to say no, this one does not. So I strongly recommend this case for Micro-SD, SD and CF cards via insert/indent provision, but it will protect XQD cards inside, as well, though not designed for them.
Hope this helps you.
