Sure, that is possible too, but what I‘m seeing frequently in the US is a new type of combined order management and payment handheld.

It makes a lot of sense, in my view: Handling orders tickets digitally is probably incredibl useful for the kitchen (especially considering a mix of dine-in and takeout orders).

From there, it‘s only a small (ok, not really small because PCI-DSS, but at least possible) step to also having these things do payments.
