Abstract: Systems and methods according to which a mobile application is running on a driver's mobile device for authenticating ride share drivers. When a driver initially registers with a rideshare service, the driver is prompted to provide biometric information via a mobile app running on the driver's mobile device. The biometric information is then stored in a database with a ride share management server in a file associated with the driver's account. Subsequently, when the driver expresses an offer to provide a ride share trip, the server performs an authentication check based on the pre-stored biometric information. Furthermore, the system discloses herein facilitates increased rideshare revenue generation by creating referral chains for a driver when a previously-registered driver, or an affiliate of the rideshare service refers a proposed new driver to the rideshare service and the proposed new driver then registers with the rideshare service.
