When I go shopping with my smartphone and the digital shopping list in my hand, I always have one hand missing. I hold the smartphone with one hand and the self-scanner with the other and then I need to have one hand free to take the item off the shelf and put it in the shopping trolley. This is always complicated, especially with vegetables, as they still have to be weighed and labeled. Wouldn't it be a great invention if the shopping trolley had an additional holder for the smartphone? I think that would be a great innovation that no other store has yet. Thank you very much!
