I used the AMC app. It's worth the fee.
Amc app or online or in the front the movie theater they have a place to buy your tickets like an atm you can pay with a card right there or they have a window you can pay with a card or cash at.
I went directly to the website to order and let them scan the qr code when we entered. I used the free AMC app version. You could just get your ticket at the door
