STM Card
Balance checking and access to key STM card information directly from the phone.
Product

STM Balance is a mobile platform for interacting with the STM system and urban mobility. It brings together STM card functions, public transport information, routes, stops, vehicle movements and other related services in a single digital interface.
Our goal is to create a unified digital platform that expands the possibilities of the STM system: from managing the card and its balance to paying for a variety of urban services. STM Balance aims to bring urban mobility functions together in one application and provide users with a convenient tool to manage them according to their needs.
