Samsung has tied up with Transport for London to let public transport users tap in and out at stations and buses simply by touching their phone against an Oyster Card reader - even if it is turned off.
While Android Pay and Apple Pay can be used on the TfL network, they require users to wake up their phone, something Samsung said slows commuters down.
To operate Samsung Pay for regular transactions, users must simply swipe up from a phone’s lock screen and verify a payment with the security pattern or iris or fingerprint scanner. They then have 30 seconds to touch the phone against a contactless terminal.
