How do I add DRM protected EPUBs to my eReader using SD cards?

Adding DRM protected EPUBs to an eReader using SD cards 

After you purchase an Adobe© DRM protected EPUB eBook in the Kobo Store, you can read it on any device with the Kobo app, or on any Kobo eReader. You can also put the eBook onto an SD card and use the SD card to read it on any Adobe-authorized device.
You can also use the Kobo app or any Kobo eReader except the Kobo Vox to read an Adobe protected EPUB from an SD card. Note, again, the device must be authorized by Adobe for the account used to open the EPUB.
To put an EPUB purchased in the Kobo Store on an SD card, you have to create a Kobo eBook version.
To create a Kobo eBook version of an Adobe DRM protected EPUB:

1. Open Adobe Digital Editions (ADE) book manager. (Note: you must have it installed on your computer or device. Go to http://www.adobe.com/products/digitaleditions/ to download ADE.)
2. Sign into Kobo online (www.kobobooks.com).
3. Locate the EPUB in your Library.
4. Click Adobe DRM EPUB. The eBook opens in ADE.
5. Close ADE.

To transfer the eBook to an SD card:

1. Locate the EPUB file in ../Documents/Digital Editions.
2. Put a copy of the EPUB file on your SD card.
3. Eject the SD card.

To load an eBook or EPUB from an SD card:

1. Open the Kobo app or start up the Kobo eReader where you want to read the eBook or EPUB.
2. Insert the SD card. The Kobo app, or Kobo eReader, will automatically read the SD card.
3. Click the eBook or EPUB you want to read.

Note: If the device you are using is not authorized with the account that contains the EPUB, you'll get an error message telling you that the book can't be opened.
