I have a samsung galaxy g s iii, my mother has a nook color. I want to read the books she purchased on my phone. I can get the book to show up in my nook app, but when I click to open it I get an error that says "Could not open book at this time. Problem with credit card." On my dad's nook when we side load books, it just has him unlock the book using my moms credit card. Is there a way to do this in the nook apps, or just on the nooks themselves?
The best way to read the books in your mom's account on your phone is to log in as her. Then just download what you want to read and start reading. You will have to stay logged in while you're reading books in her account, though, as If you log out the app will delete all the books from the phone.
