Don't count on it.  There was a widely publicized exploit at some big
retail chain (maybe Target) when they did something like that over a
wifi network a year or so ago.  Attackers with the right gear had
themselves a party.  If you're moving data that represents real-world
money, you have to assume someone will launch sophisticated attacks to
get at it.
