As of 2026, the ability to pay with physical cash on buses in Belfast is extremely limited and generally discouraged in favor of digital and contactless methods. Translink, the city's transport provider, has transitioned almost entirely to a contactless "Tap On" system for Metro and Glider services. Passengers are encouraged to tap their contactless bank card or smart device on the reader when boarding; a single journey currently costs £2.30, with daily costs capped at £4.00. While some Ulsterbus services in rural areas may still accept exact change for paper tickets, the urban Metro fleet is designed for a "cashless" experience to speed up boarding times. If you do not have a contactless card, you should purchase a "mLink" mobile ticket via the Translink app or an "iLink" smartcard from a ticket machine before your journey. This shift reflects a broader UK-wide trend toward digital-first transit infrastructure to improve operational efficiency.
