Korea’s No.1 rental car company, KT Kumho Rent-a-Car, has been revamped as the largest online branch in the country. The overall site concept is “Easy of Use.” Since rental car users span across all age groups, the site is designed with the principle that anyone visiting for the first time can navigate quickly and easily. To maximize user experience, an easy and fast User Interface was implemented to enhance accessibility, along with a simple and modern Graphic User Interface to maximize visual communication. Separate versions for PC and mobile were developed to provide the most suitable content for each device. Additionally, through service integration with Hertz overseas, the site offers both Korean and English versions simultaneously.
