It would be very useful feature for us as well. Passing to info to Stripe if payment is a membership or court reservation or classes/events would be very helpful for book keeping. Ideally, it would be good if Stripe can pass the payment to two different accounts depending of the type of payment that was made. However, they need to get additional info from CR system that is passed during payment transaction.

As mentioned, there is a lot of unused space on the screen and. I would add, having a real time clock (time, date) displayed while waiting for bar code to be scanned would be useful as well. Making kiosk page responsive (to resolution) is what all modern html do.
