Not sure if I quite follow.

We don't let our customers write checks directly. They can send checks from our apps, but they don't get a checkbook. Even if someone produced checks with one of our customer's account numbers, our systems are set up to reject them.

We are working on a way to let our customers write their own checks, but we're taking our time on this feature as we want to shut down that fraud path with a special type of check. More details to come in the future.

The feature we released today is for check deposit. Yes, you could suffer if someone gave you a fraudulent check, but the risk is no different than depositing that same check at a teller.
