Whatever the House decides on could be an option, and that is definitely one of them. Certainly, as I said, it could be the roll call where you have the face showing up—you know it's them, and they're speaking—or where they're at their screen and they push a button “yea” or “nay”. There might even be some biometric or some code that has to be put in to verify the person.
Again, depending on what the House decides, yes, that is an option.
