Tapped using Google pay, shows right away when checked by fair inspector
I've always known that if I pay using a credit card on Google pay or Apple pay it doesn't get uploaded to the system instantly and it doesn't show on fair inspectors' device right away. Although it shouldn't be like this but my credit card gets charged at night so that makes sense. It has happened to me before that the inspector checked and it came with a big red X then I told them I paid Google pay and they let me go.
Today it wasn't busy at the station so I approached an inspector asking I just paid using Google pay, will it show in your machine. It did show that I paid. Now I'm wondering how it actually does work.
