IT has been promised to commuters for more than 12 years but the electronic ticketing system called Opal is slowly being rolled out.
Based on the Oyster card being used in London, the card would allow commuters on public transport to charge their card and move from route to route without buying a new ticket for each.
Transport Minister Gladys Berejiklian announced an initial trial of the $1.2 billion system on the Neutral Bay ferry loop this month and a full roll out across buses and trains by 2015.
As he waited for a bus in Argyle Street, Mike Rogers, of North Parramatta, said it was a mystery why commuters had to wait so long for a decent ticketing system.
"London has had one for 15 years and they've got one in Melbourne on the trams," he said.
"It can't be a big deal to bring them in here. Cars use the same thing with the e-tag, it can't be difficult."
Mr Rogers said it would be a fine day if the government got the system right.
"You can just charge your card every couple of weeks and away you go," he said.
Also waiting at the bus interchange was Rob Hamilton who hoped missing the bus would be a thing of the past when the Opal card was operational.
"There's nothing worse than when you have to run off to buy a ticket. Then you get back to the bus stop just in time to see your bus driving off," he said.
Trains will join the system's trial from the middle of next year and buses in 2014.
