This document summarizes testing of an MVP 2 for a mobile scanning and payment application for use in supermarkets. User testing showed high satisfaction ratings for features like customer reviews and an interactive interface. Some issues were encountered like not being able to change quantities in the cart view and long review comments not fitting. The developers learned to keep designs simple but not too simple and the importance of repeated testing. The application is not yet ready due to unsolved payment and anti-theft problems and the need for supermarket cooperation. Supermarket staff said the app needs to provide useful data and prove its profits exceed costs.
