Customizing POS View

I’m almost there with setting up & customizing for production, but I still can’t figure out a way to customize the POS view.

In particular, after clicking the pay button, I’d like to add additional payment details together with the amount paid and mode of payment. Basically, for non-cash payment, I’d like to input info like card payment approval code/transaction ID etc.

Would really appreciate it if someone can help point me to the right direction?
