Dublin Bus may stop taking cash payments in a new plan devised to reduce journey times.
The Herald reports that the National Transport Authority (NTA) are considering changing to an 'account-based' ticketing system.
Travellers will be encouraged to use Leap Cards and eventually even contactless bank cards and mobile phones.
Already, 70% of all journeys are paid for with Leap Cards and the initial plan is to encourage more people to use the prepaid service over the next three to five years. Part of this process may be increasing the cost difference between those who pay with cash and those you use Leap cards.
Ann Graham, Chief Executive of the NTA said: "This has happened in London and it's worked".
