Travelling with Queensland go-cards might become simpler as part of a major public transport upgrade with the 10-year-old go-card system set to receive major improvements.

In Queensland, the new card and smartphone scheme aims to introduce new tap-and-go bank card and smartphone payment services, to be trialled initially on Brisbane's Airtrain service before then being adopted throughout the state.

It is hoped that phasing out go-cards will streamline payments and allow commuters to travel with one less travel card.
