Product scanner - Queue killer

Hello Dribbblers 🏀!
Recently, I've come across a common problem appearing in hardware stores.
It would save you a lot of time ⏰ if you didn't wait firstly for the shop assistant to help you find an item, and then avoid staying in a long queue to checkout, right?
The main goal of the project was to improve the shopping experience. I found a relatively simple but yet effective solution for this, showing it on the B&Q example - one of the biggest hardware retailers in the UK.
Any thoughts on this topic 😎?
