ExxonMobil lets you buy gas using Apple Pay at the pump - CNET

Apple Pay went live Tuesday in more than 6,000 Exxon and Mobil-branded gas stations across 46 US states. The service will be added to about 2,000 more stores by mid-year and will be available in nearly all of the company's 10,000 locations by the end of 2016, Russell said.

The ExxonMobil system is unlike Apple Pay as it was first presented. In that initial method, you wave an iPhone 6 or later device at a register to pay for goods. The phone talks to the register using a technology called near-field communication, or NFC. You also can use Apple Pay to make purchases in apps without having to enter your credit card information each time, which is the feature used by ExxonMobil. Apple Pay is accepted at more than 2 million US locations.

The new method, by contrast, uses the phone's location and the ExxonMobil app to let you make a purchase before you get out of your car.

ExxonMobil is the first gas company to broadly roll out a mobile payment system. Chevron last fall partnered with Visa to bring NFC technology to gas pumps in Califoia, allowing you to tap your phone to pay with Apple Pay, Google's Android Pay or Samsung Pay at more than 20 stations around San Francisco and Silicon Valley.

ExxonMobil's updated Speedpass+ app uses GPS to track your location and determine which gas station you're visiting. You select the pump number and confirm the purchase using the iPhone's Touch ID fingerprint reader. In places where geolocation doesn't work well, you can scan a QR code, or a customized symbol you pick up with your phone's camera, at the pump or search in the app for your location.

You have to start fueling within about 45 seconds or the app will time out and you have to start the process over. You'll be able to get a paper receipt from the pump and will be able to track your purchase history through the app.
