The 고속도로 통행료 app is designed to streamline the management of highway tolls and Hi-Pass services for Android users. This free application enables users to inquire about unpaid tolls, make payments, and check their Hi-Pass card usage history. It also allows users to print receipts, check for refund eligibility, and apply for refunds, making it a comprehensive tool for highway travelers. Additional features include the ability to recharge ex-cards, monitor balances, and access highway toll-related notices and FAQs.

The app requires certain access permissions for optimal functionality, such as access to photos and videos for refund reviews and print receipts, phone access for simple payment services, and camera access for attaching proof of refunds. Users will receive notifications regarding their Hi-Pass usage history and other relevant updates. Note that the app is optimized for Android version 8.0 and higher; users with older versions may encounter network issues.
