For those seeking the mobile application, the process involves visiting the Google Play Store or the Apple App Store. The official app, often named after the specific transit authority (such as TransJogja or similar BRT operators), allows users to register their physical card, check remaining balances, and view transaction history. To "download" this functionality, users must search for the official app using keywords like "BMT Card" or the specific transit system name, ensuring they select the verified application to avoid security risks. Once installed, the app does not replace the physical card but rather serves as a management portal; users must still carry the physical card to board vehicles.
