US/AA at MCI (where each group of gates has its own checkpoint) is Pre-lite, where you can leave shoes on and use the WTMD but have to take laptops/liquids out of your carry-on. They mark it by scribbling the BP with yellow highlighter and require you to keep it visible the whole time; if you use mobile BP, they give you a pink card that you have to keep visible at all times until you're through.
