ajobbins: The Thales solution is just a transport card. Nothing more. They don't want it to ever be any more than just a card to pay for transport within the Auckland region only.
Snapper on the other hand is a flexible payment solution for transport and other micro payment - and then some. They are much more open to other uses for the card such as loading of other applications to the card chip. Could be used for building access, flybuys (or other loyalty), Airlines (Eg. mPass) etc etc if they choose. The Thales card will never be any of these things because they have specifically designed it that way.
That's fine. I don't want the Snapper card to be used as a de facto surveillance device...as has happened in other places.
