Start with the UCC as enacted in your state. Assume that those requirements will continue to apply. Then, look at E-sign. It suggests that you can agree with your customer to accept stop orders (a written document) electronically, with whatever electronic signature you are willing to accept.
You'll want a way to verify customer ID when accepting e-stops. You don't want me sending a stop order on your checks. It may be best to accept stops from within your e-banking application, into which the customer will have been password-verified. Many of these systems have the stop order automatically input to the system, so that manual intervention by your clerks is not needed.
Be sure you put some strong caveats on accuracy of data on your web-stop form. You know the drill. It's probably already plastered on your paper stop form. And, if you already have a customer service number published for the e-impaired -- i.e., your call center -- use that for the customer who either needs to correct his e-error or wants to lift (cancel) the stop.
