Pull up QR code without wifi

Picture it: You walk up to the register to order, whip out your phone and activate the app. (the app now makes the card redundant, right?) Not so fast- It wont did load the QR code unless you have established a wifi connection. Uhhh.. Hold on, let me deactivate wifi. *fumbling feverishly while other customers pile up behind me*. Never mind -*pulls trusty card from wallet*

I get it-its cool to have live updated account information, but its quite annoying that I cant pull up the QR code quickly to get my business done.
