Barcode scanner is a scanner that enable scanning of barcodes on pack goods or products that shows all the bedded information on the screen, such as contact info, data matrix and so on. There is an option to share, bookmarks contacts on the application.
Here I suggest to add the feature lights / reverse camera / help. so users more easily in using this application.
Before
After
If the user select light feature
If the user select help feature
Usability or rather the benefits of the feature:
is to make it easier for users to scan the code even in the dark.
is to facilitate the user in reverse the camera, for example, here I suppose if there is a user who experienced damage to the device on the rear camera, then the user will be able to scan the code with the front camera, and I think this is very functional in this application.
is to facilitate the user in learning how the steps to use this application.
