Uber operates an international transportation network using a mobile app. It was founded in 2009 and now operates in 64 countries. The app allows customers to request rides from drivers and pay electronically. Uber uses various technologies like GPS and transaction processing systems to coordinate rides. It also uses marketing strategies like promotion codes and feedback systems. Operations involve allocating drivers, evaluating programs, and managing day-to-day issues. The app provides services to both customers and drivers, including pickup locations, cashless payments, and support centers to handle issues.
