While originally standardised in design, they soon featured advertising on one side of the card. Such cards were eventually replaced in 2002 when a new system of contactless smart cards known as ez-link cards were launched.
These tickets were part of the launch of the system in 1987. The came in a variety of colours to indicate different fares: adult (teal/blue), children (pink) and senior citizens (purple). Besides stored-value tickets, there were also single-use tickets (green) that were valid only on the day of purchase. There was also a gold commemorative version.
