“A mobile app named Cartculator, is an app where a scanner can scan the price of any product from the aisle while they’re shopping and it will give them a total calculated amount before they check out. In this way the shopper will know the exact total amount of what they’ve shopped.
Each time the shopper scan the price of the product, the price of the respective product will add up in the calculator installed in the app. Not only it will add the price but also shopper can subtract the items if they changes their mind.”
