Victorian public transport smart card update

Victoria's $494 million public transport smart-card ticketing system will apparently use the same technology as does London's public transport system.
Sources who should know tell me that the contactless smart-card system will display the account balance of your card as you pass through the turn-stiles.
These sorts of details are unusually scarce at the moment because of the controversy over the tender.
As readers may or may not be aware, the Sun-Herald published details of the penultimate bids lodged by the various contenders. And the winning company, US based Keane consulting, did not have the lowest bid.
The whole business has now been referred to the Victorian Auditor-General, because clearly the tendering process was not carried out with proper confidentiality.
And in the wake of that the winning tenderer, Keane, has clamped down very tight on speaking to the press.
They'll only do it via a PR company, with questions required to be submitted in writing in advance.
So details of the system that Victorians are going to get have thus far been very scarce.
However I've learnt today that what we are going to get is essentially the same as what Cubic Transportation Systems have installed in London.
