NFC Times Exclusive – Both Apple and Transport for London are trumpeting the coming use of Apple Pay to pay fares on various modes of mass transit in London, including the fast-paced London Underground. But they face a couple of problems.
All payments with Apple Pay require users to authenticate themselves, which they usually do with a scan of their fingerprint or thumbprint using Touch ID. But according to tests by UK-based consultancy, Consult Hyperion, Touch ID authentication generally takes more than 900 milliseconds to complete.
That plus the payment transaction itself would put the full fare-collection event well over the maximum Transport for London has said it would accept–500 milliseconds–to keep customers flowing through its busy metro gates.
