It's a stretch but it'd be awesome if app.hint.com could be made into a native iOS mobile app that enables you to manage Hint billing management from your iPhone or iPad.
A Stripe integration which enables physical card swipes could lower the cost of processing fees and manual signatures could be collected.
A mobile app would make it easier to capture images of insurance cards or photo IDs, both which would help prevent fraud and chargebacks, increase patient security, and make Hint a more powerful patient management tool.
