Does anyone know of or use a good online, web-based credit card terminal?

I DON'T WANT TO ACCEPT CREDIT CARDS THROUGH MY WEBSITE. I just want to dump my terminal on my land line and switch to a web based service. I have seen them used before, and many looked nice, I just can't seem to track any down. Looking for something like this:

Ideally something without monthly minimums, monthly fees, etc.
Ideally something that can take advantage of Android.
Ideally something that would allow a small card reader to be integrated into it for a lower swipe rate.

Thanks for any insight!!
