Transport for London (TFL) is warning that a number of variables can impact adversely upon the use of the newly launched Apple Pay in the underground.
The body has warned that individuals using contactless mobile payment services such as Apple Pay will be charged the full price of the journey if their battery expires during journeys.
Furthermore, a warning was issued to ensure that commuters use the same device that was used to pay for the journey, as transactions are tracked in such a way.
TFL said: “[if your devices] runs out of battery in the middle of a rail journey, you will not be able to touch out at the end and could be charged a maximum fare [and] if an inspector asks you to touch your iPhone or Apple Watch on their reader, it will not be able to be read and you could be liable for a penalty fare.”
Following the launch, the expediency of Apple Pay’s thumb scan for commuter travels has been criticised. Furthermore the service is notably slower than pre-existing contactless cards – such as the Oyster card.
