Kum & Go, a Des Moines-based convenience store chain, has launched a new mobile fuel pay app that will allow its &Rewards members to avoid using the keypad and instead activate the pump with their smartphone. The app can be used at any of Kum & Go’s 400 locations. In a release, Kum & Go President Tanner Krause said that in today’s world, “limiting common contact points is essential.” The app allows customers to limit their contact with the pump as well as avoid spending a lot of time outside their vehicles in inclement weather. The secure mobile payment platform uses Kum & Go’s existing mobile phone app.
