Unfortunately it probably won't happen for awhile :(. We're a free service, and make money off the interchange from issuing these cards. Amex and high points cards are really expensive to accept funding from.
Got it. Would it help you to know I'd be willing to pay for something like this for all of my cards? That may be a good freemium model to explore.
That is great to know! If we do add support for credit cards, it would probably be as a sort of premium feature.
