Do you want to Let Your Phone Pay for Your Car’s Fuel? Automation is becoming a bigger part of the driving experience. A mobile phone app called Shell allows drivers to pay for a fill-up of gasoline from their in-car touchscreens. No debit or credit cards are involved, so the process will work for drivers who forgot their wallets.Here’s how it works, assuming the user already has downloaded the Shell app and connected the mobile phone to the car’s network. The car’s touchscreen will guide the user to the nearest service station. After pulling up to the gas pump, the user enters a PIN code and the gas pump’s number. Payment takes place through ApplePay or PayPal, and a receipt is displayed onscreen and sent by email.
