BKK’s contactless Pay+GO service, currently available on the 100E airport express and the M1 metro line, will expand to all metro lines by mid-April, the authority told MTI.
The system allows passengers to pay and validate tickets in one step using a bank card or smartphone, meaning that no registration, app download, or paper ticket is required.
Building on pilot results and international best practices, BKK has finalised its e-ticketing concept, which the city assembly endorsed on Wednesday.
The full system, set for a phased introduction from early 2028, will cover Budapest and its surrounding area, offering flexible fare options, including daily or weekly spending caps, for both regular commuters and occasional travellers, they said.
