Device and method for implementing a vehicle sharing reward program. The present invention provides for a cost-sharing plan where two or more constituencies share the rental cost associated with a user who rents a shared vehicle in a vehicle sharing program. This results in a reimbursement of the rental cost to the user. When enrolling in the vehicle sharing reward program, the user is given a health prescription to adhere to on any trip taken while using a shared vehicle. On a selected travel route, the user visits a vehicle sharing station, where the sharing station includes a kiosk that the user uses to check-in and upload relevant information such as distance traveled and locations visited. By complying with the health prescription issued to the user, the user can have its total rental cost reimbursed.
