The fact that there are no names doesn't exactly instill trust or confidence.
Closest I could get to info would be that the Southern Payment Systems Pty Ltd resolves on a google search to: http://www.southernpaymentsystems.com/ which seems to share the street address of a Designer(http://speakinteractive.com/), a real estate agency(http://www.eftosestates.com.au/) and a ruby on rails developer(http://brownbeagle.com.au)
[update: never mind, found one of the co founders, http://dompym.com/ pretty impressive, he's ex SAP and ex Clear Interactive, acquired by the NZ exchange]
