cisconz: The other issue is that Eftpos New Zealand charge an extra $10 per month per machine to have an eftpos terminal connected via IP, no idea why as it is cheaper for both the client and ENZ to run it over IP.
This is part of the issue as retailers don't see the benefit of running over ip so don't.
I know that TWL Silvia Park run 20 terminals over a single dial up connection that stays online all day everyday - waste of resource in my opinion.
