- The encryption is complety enclosed within the ebooks file. To access the ebook you need to know the credit card number and name the book was encrypted with. The ebook is not tied to the hardware of your ereader (Kindle) or to a software ID (Adobe DRM).
This means that you can copy the ebook file to as many ereaders as you want to, as many times as you like. This makes it easy to share the ebook with anyone you trust with your credit card number and name (that is how this social DRM limits the sharing of the ebook, there are no technical restrictions against sharing).
- Because the encryption is completely enclosed within the ebooks file, after dowloading the ebook file you do not need B&N or an DRM server anymore. Even if B&N and the credit card would no longer exist you will still be able to read the ebook on any device or program supporting the DRM.
- So if you want to remove your credit card from your B&N account, which basically means you do not want to use B&N’s e-book cloud anymore, make a backup copy of your ebooks with for example Nook for PC (which you should do anyway) before removing the credit card. Those copies will be yours forever. You can copy them to any device or program supporting the DRM and with all those devices and programs you will be able to read those ebooks. No DRM-server, software-ID or Internet connection is needed.

But the e-reader needs to be authorized with the credit card number, and it has to match what's on the BN account.
I got my e-reader (which read BN's DRM) two years ago, and at the same time had changed my credit card on the BN account, and entered that into the e-reader. I had a bunch of books I'd downloaded with the Nook for PC program, with an earlier credit card. I could not read any of them on my e-reader; I had to redownload everything.
