From the CASA web site:
Replacement of an ASIC - $108.00
From the link above:
As at 30 June 2010 there were 265 328 valid issued cards (126 806 ASICs and 138 522 MSICs)
Also from the link above:
There are 25 entities that have the machines to make the cards
265,328 / 25 * $100 = $1,061,312
Not a bad earner to own a printer.
