스마트링크 Smartlink is a vehicle rental and control service provided by SK렌터카주 for corporate customers. The service is based on the concept of car sharing, allowing employees to conveniently reserve and use vehicles outside business hours. The system is designed to reserve, use, and return a vehicle, and the fare and vehicle provided will vary according to the purpose. The service features smart key function, service notification, and before/after user notification. The service functions include sign up and login, vehicle reservation, vehicle use, vehicle return, administrator program, and announcements/events, 1:1 inquiries, and frequently asked questions. However, some vehicles cannot use the full control function or the remote control function, and some vehicles and customers using the auto return function cannot use the service. Smart Link Customer Center is available for assistance during weekdays and Saturdays.
