Drivers can now pay for their fuel at the pump in the UK via a smartphone, following a partnership between Shell and PayPal.
The service is offered at participating Shell service stations in the UK via the Shell Motorist app for iOS and Android. Shell says the service will be available for Windows phones in the "near future".
It works in a few simple steps once you've registered with the app and have paired it to your PayPal account.
Once the driver arrives at the pump they stay in the car, open the Shell Motorist app and select 'Fill Up and Go'.
They then choose a maximum amount to authorise and scan the QR code at the pump. When the 'start refuelling' message appears, the driver leaves the phone in the car and refuels as normal.
The pump will stop dispensing once you reach the maximum fuel spend limit selected, and if you fill up less than that maximum amount you will only be charged for what you’ve used.
