No you haven't, you just said "except if it's cordless" without
explaining why they don't count for whatever it is we're talking

I meant "stand-alone" as in "not relying on a till to enable the
transaction". I don't see how it matters if the terminal's connection
to the bank is wired, WiFi, bluetooth, GSM or whatever.

As to how you could connect a victim's contactless card to a terminal
that is "far away", surely it is not hard to conceive of a device
which you hold near the card which does nothing but receive and
transmit to the card, and then forward this conversation on via,
e.g. WiFi, to a terminal further away - even assuming that for some
reason you couldn't put a wireless PDQ terminal in your pocket.
