    I have a food cart and want to improve the customer payment interaction. I want the customers to be able to input into a credit card app on a phone in front of them, while I also input into that app on my phone (e.g. Square Register).
    Is there a way to do this? I know that I can lock the customer phone on the app and I know that I can have a display app running on both screens, controlled from my phone. But I can't find a method -- app, different device configuration, etc. -- whose specs guarantee the result I seek.
