Is the terminal the waiter brings to your table exchanging telemetry
wirelessly during the transaction, or does it have to be plugged into
a base station elsewhere in the restaurant? I assume it's wireless.
They are connected wirelessly (to a base within the retailer's
premises), Bluetooth apparently:

Are they robust enough to be used where fare collection with a hand-
held device is warranted, if gawd forbid we talk about transport, or
would a more robust hand-held device be used on trains?
Outwardly similar devices are available (they don't use regular retail
handhelds communicating with a base station on the train):
