Android: Continuing the never-ending onslaught of new Google Now cards, Google has begun rolling out a feature that will remind you of upcoming bills. Provided you have email scanning turned on, of course.
The feature probably won't be able to check all bills (notably because not all bill reminder emails include due dates or amounts due), but it can be a handy reminder for those that it does support. The features seems to be quietly rolling out and may not be available to all users just yet. If you have email scanning turned on, though, take a look!
