The writer stressed that retailers from Newcastle to Gosford don't sell these travelling types of cards.

And it's not that far off until September 1.

Furthermore, they apparently aren't sold at railway stations. Where's the logic in that?

Also, the writer spoke of the waiting time to obtain one of these cards.

What about elderly people or people who can't use the internet?

And what about tourists from other countries?

I recently travelled to a city in China called Guangzhou. There is a fantastic metro underground rail system there.

When buying a ticket, it's made of plastic, a circular shape, and about the size of a 50-cent coin. The ticket machine was very easy to operate.

All I had to do was put the ticket through a barrier and catch a train to my destination.

At my destination station the ticket barrier captured my ticket.

Maybe a straightforward system such as this could be put into use on the suburban and intercity systems in NSW?
