The Chi MPEA Tax App gives Chicago taxi drivers an easy way to buy stamps to pick up passengers at the Midway and O’Hare airport terminals. With this app, you can create an account using your driver’s license and buy Metropolitan Pier and Exposition Authority (MPEA) stamps.

You can display stamps on the app to be scanned, or print them at airport kiosks. You can save payment information and see the stamps you have bought and used.
