Pay for your ride with Express Transit
With Express Transit (available in certain countries or regions), you don’t need to authenticate with Face ID, Touch ID, or your passcode, and you don’t need to wake or unlock your device or open an app.
If you have multiple cards for a transit network, set the default Express Transit card in Settings
> Wallet & Apple Pay > Express Transit Card.By default, Express Transit is turned on when you add an eligible card.
As you approach a fare gate or board the bus, make sure your device is turned on (it doesn’t need to be connected to the internet).
Hold the top of your iPhone near the middle of the ticket gate scanner until you feel a vibration.
On models that support Express Cards with power reserve, your Express Cards may be available for up to five hours when your iPhone needs to be charged. To check if Express Cards are available when iPhone needs to be charged, press the side button (doing this often may significantly reduce the power reserve for Express Cards). If you turn off your iPhone, this feature isn’t available.
