As Uber is serious about enabling on-demand transport for everyone, everywhere, we have been trying to find easy ways for people to pay their drivers for trips. When we figured out that only 24% of the world had a digital payment method, we realised we needed to support cash to enable everyone else to take trips using the Uber app. Enabling cash services across 50 different markets while providing great customer service put us in an interesting and challenging situation. In our keynote, we will tell the story of how we were able to make cash payments a reality through listening to our users, both riders and drivers. We will then touch on how we leveraged our engineering & tech team talent to come up with a solution.
