The last piece of friction you need to remove is the staff having to bring you the check. Sometimes it's frustrating to have to wait 5 or 10 minutes after you're done eating to flag someone down just to get your check. You want a way to be able to get access to your check without having to speak to anyone. Maybe instead of the NFC is the receipt holder, you have a version of it that can be embedded into the table itself. Something as simple as a RFID chip in a sticker could accomplish that. When I'm done eating, I just lay my phone on an area of the table that says "place phone to pay".
