The model is similar to iTunes. You can create your account on the website on your computer for typing convenience, and you can do your purchases on your computer. But as far as I can tell, it will remember your credit card number. You can't prepay.
You can sign out of your account on your smartphone every time you use it but all your books will be deleted until you sign in again, when they will all be downloaded again. (at least that's how it works on my iPhone)
