Some 70% of passengers already pay their fare through Leap cards.
Dublin bus looks set to go cashless as as part of a new plan to reduce travel times across the city.
But the National Transport Authority wants to follow the example of London by stopping cash completely - which can regularly result in delays as drivers take coins and issue tickets.
The plan is to get all commuters using Leap cards or a new account-based ticketing system, the Herald reports.
And if you insist on using cash, you might be forced to pay higher fares.
There are also plans to allow passengers to buy tickets at shops before they get onboard.
The changes are expected to take place over the next three to five years.
