On the browser-based version of Interac verification service, I see that there’s a mobile version of the service. What are the differences between both experiences?

Through the browser-based version, you’re able to complete activity on a web browser – where the service is available – and have your progress saved for future visits. 

The mobile app offers a more personalized experience.  The mobile app enables you to help verify your identity to access certain services and products, and provides access to more features, including the ability to see your Connections and transaction history. With the mobile app installed, you’ll also be able to use it to expedite processes that were started using the browser-based version of the service. We recommend installing the app to ensure you get the best possible experience with the Interac verification service.
