Shell, PayPal team up so customers can pay at the pump using a phone

Shell and PayPal want drivers in the UK to embrace the "Fill-Up & Go" mobile payment program, giving customers the chance to scan a QR code into the mobile app. Once a customer scans a QR code at their gas pump, they can select how much fuel they wish to purchase, and then pump the gas.

Monetary amounts are tied to each customer's PayPal account, and is designed to streamline gas purchases for commuters - and those not interested in going inside.

Both companies initially announced their testing plan in early 2015, and with half of Shell customers only purchasing gas before leaving the station, a mobile offering seems like a clever idea.

Chevron and Apple are currently testing a mobile service using Apple Pay, as other gas companies and mobile payment services try to sort themselves out.
