Those wanting to be able to ditch their Oyster and use a mobile handset for travel payments will need a device with an NFC chip, which currently excludes any iOS devices. They will also need a compatible Visa, MasterCard or Amex mobile payment app. Carrier EE has been touting its compatible Cash on Tap app, although this is only being offered to users of its 4G network who own select 4G Android handsets. Currently contactless bank cards are already accepted by TfL as an alternative to its Oyster cards on London buses, replacing cash as a payment option earlier this month. But from September 16 the whole TfL network will accept them, along with compatible mobiles.
