I read with some interest the article in the Herald today about Paymark, whereby customers in NZ will (eventually, sometime next year by the looks of it) be able to use their mobile phone to make cash payments for things in stores.  This is fine, as far as it goes.

I am involved with a startup company that sells a new drink product (no not an energy drink!) and we are looking at selling (as well as in retail stores) at markets, at events etc.  Now I have seen overseas the likes of Square which takes credit card payments via a small piece of hardware that adds onto your iDevice.  Square then direct credits the monies into your account the next day.

Paymark is not going to suit my purposes for the drinks company as I want a mobile way to ACCEPT rather than make payments. 

Just wondering (other than having to buy/rent a mobile EFTPOS machine) whether there are any other services in NZ like Square that would allow me to use my iPhone or iPad to receive payments for items when on the road?

If not, what suggestions do you have for other ways of electronically accepting payments?  From what I recall renting/buying mobile EFTPOS machines is pretty expensive and as a startup we would like something simple and cheap.  Be interested in your opinions, views and knowledge on the subject.
