EE customers travelling on London buses are now able to pay their fare by tapping their phone against the bus’s Oyster card reader.

Those wishing to use the alternative payment method need an NFC-enabled smartphone and EE’s Cash on Tap app . 

EE did not disclose how many of its customers currently have access to the digital wallet, which must be topped up before travel, but it did reveal that the service is expected to be compatible with over 500,000 customers’ handsets by the end of 2014

The mobile operator was keen to stress that there will be no added charges for using Cash on Tap to pay for travel, highlighting that daily and weekly caps are in place so that customers don’t pay any more than would if they were using their Oyster card.

“More people use London’s buses than all the other bus services across the country combined, so the need for speedy and simple payment solutions is paramount,” said Pippa Dunn, EE's chief consumer marketing. “That’s why we’ve been working hard to bring our contactless mobile payments service, Cash on Tap, to TFL’s network – removing the need for customers to queue for a ticket, or hunt through their pockets and bags to find the right card”.

EE's Cash on Tap app can already be used to pay for things at the likes of McDonald’s, Caffè Nero, Pret A Manger and Greggs. 

From September 16, it will also be possible to use Cash on Tap to pay for journeys made on the London Underground, DLR and tram network.
