+  - If all fields could be automatically populated (means for purchase the product has a default best before date set), the transaction is automatically submitted
+    - If not, a warning is displayed and you can fill in the missing information
+  - Audio feedback is provided after scanning and on success/error of the transaction
+
 ### New feature: Self produced products
 - To a recipe a product can be attached
   - This products needs a "Default best before date"
