In 2015, Uber was quickly entering new markets, some of which had low credit card usage or a cultural inclination towards cash transactions. However, allowing cash payments would add operational complexity, pose potential security threats, and necessitate substantial changes to Uber's products and procedures. To start, I would gather data to determine the proportion of our target market that either cannot or chooses not to use credit cards for payments. Additionally, I would engage with drivers to gain insight into their opinions and concerns regarding cash transactions. Would the possible revenue from users who prefer cash be substantial enough to justify the associated costs and risks? Next, I would examine operational considerations: How would drivers handle cash? How would Uber collect its commission? How would we address customer complaints and process refunds? Lastly, I would explore alternatives such as collaborating with local payment services or allowing users to add cash to their Uber accounts at nearby stores. My final decision would be based on the proportion of cash-preferred users, the anticipated revenue from these individuals, the expenses and complexities tied to implementing cash payments, the associated risks, and the practicality of alternative solutions.
