Phones and credit cards to pay for public transport

Victoria (in Australia) wants to lead suckers to use phones and credit cards to pay for public transport. If they do this foolish thing, the system will track all their movements.

Will this system permit anonymous use, paying cash? Will it permit use by someone who has no snoop-phone, snoop-watch, or snoop-card? If so, how would that work? And what is possible with the existing system? If you know by experience, please email me.
